6. NOTES ON BATTERIES AND RECHARGEABLE BATTERIES

• Keep batteries/rechargeable batteries out of the reach of children.
• Ensure that the polarity is correct when inserting the batteries/rechargeable batteries (observe plus/+ and minus/-).
• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of batteries being swallowed by children or pets. If swallowed, consult a doctor immediately.
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin. Wear suitable protective gloves when handling them.
• Liquids leaking from batteries/rechargeable batteries are chemically highly aggressive. Objects or surfaces that come into contact with them may take severe damage. Therefore, keep batteries/rechargeable batteries in a suitable location.
• Make sure that batteries/rechargeable batteries are not short-circuited, disassembled or thrown into fire. There is a danger of explosion!
• Never recharge normal (non-rechargeable) batteries. There is a danger of explosion! Only charge rechargeable batteries which are intended for this purpose; use a suitable battery charger.
• If not used for a longer period (e.g. in case of storage), remove the inserted batteries/rechargeable batteries. There is a danger of old batteries/rechargeable batteries leaking, which causes damage to the product, loss of warranty/guarantee!
• Always replace the entire set of batteries/rechargeable batteries, only use batteries/rechargeable batteries of the same type and by the same manufacturer with the same charge status (do not mix charged with partially charged or empty batteries/rechargeable batteries).
• Never mix batteries and rechargeable batteries. Use either batteries or rechargeable batteries.
• For proper disposal of batteries and rechargeable batteries, please read the chapter "Disposal".

It is possible to operate the combination meter with rechargeable batteries. However, the lower voltage (battery = 1.5 V, rechargeable battery = 1.2 V) causes the operating duration and display contrast to reduce strongly.

Therefore we recommend not to use rechargeable batteries for reasons of safety, but to only use high-quality alkaline batteries in the combination meter to ensure long and safe function.

9. INSERTING BATTERIES, BATTERY CHANGE

• Open the battery compartment on the top by first turning out the two screws (2) via the enclosed hexagon socket wrench and then taking off the battery compartment lid (1).
• Insert four type AAA/Micro batteries into the battery compartment in the correct polarity (observe plus/+ and minus/-). Small symbols next to the battery compartment indicate the proper alignment of the batteries when inserting.
• Attach the battery casing lid and screw it back on. Observe that the sealing ring in the battery compartment lid is placed properly.
• The batteries require changing when the display contrast is very weak or the device can no longer be switched on. For weak batteries, the symbol for the battery condition display (E) flashes as well.

a) First commissioning

The electrode of the pH measuring probe always must be kept moist to be able to deliver accurate measuring results for a long period of time.

If a small amount of liquid is in the protective cap of the pH measuring probe at delivery because of this, this is normal. If no liquid is visible, you need to fill it into the protective cap after initial commissioning.

For this, add a little bit of the enclosed storage solution into the protective cap and screw the protective cap onto the pH-measuring probe. The electrode of the pH measuring probe must not dry out anymore after initial commissioning.

The same applies to the electrode of the ORP measuring probe (not enclosed, can be ordered as an accessory).

Observe that the protective flap with the storage solution in it does not tip over. If this has happened, wipe off the liquid with an absorbent cloth and put the cloth into the regular household waste. Wash your hands with water and soap carefully.

If the storage solution is used up, you can purchase more as an accessory.

The electrode of the pH measuring probe is a wear part. Its service life is limited. For this reason, the pH measuring probe is not included in the warranty/guarantee.

b) Replacing the measuring probe

• Switch off the combination meter
• Loosen the cap nut (6) and take it off.
• Axially remove the present measuring probe from the combination meter; do not cant it. The measuring probe can be removed with very little effort; do not apply any force!
• Plug another measuring probe into the combination meter. Observe that the slot in the housing points forward to the display so that it can be pushed open easily.
• Put on the cap nut (6) in the right direction and tighten it manually. Do not use any tools and do not apply any force.

c) Switching on/off

Briefly press the button "JGAL" (5) to activate or deactivate the combination meter.

All segments of the LC display appear for a few seconds when switching on. Then a measured value is displayed depending on the measuring probe used, as well as the temperature.

The battery condition display at the lower left of the display indicates the current condition of the inserted batteries. If this display flashes, the batteries are flat and need to be replaced. See above.

The combination meter switches off on its own after 10 minutes if not used.

If the display “Err” appears in the display, no measuring probe is connected to the combination meter or the measuring probe has no connection to the connection in the combination meter.

d) Change operating mode

Brief pushing of the button “MODE” (10) permits changing the operating modes of the combination meter. The display shows the corresponding display (H).

The respective possible operating mode depends on the measuring probe used:

Measuring probe "PH":

“PH” Measurement/display of the pH value

Measuring probe "COND":

"COND" Measurement/display of the conductivity

"TDS" Measurement/display of the TDS value

"SALT" Measurement/display of the salinity

Measuring probe "ORP" (not enclosed, can be ordered as an accessory):

"ORP" Measurement/display of the ORP value

e) Selecting the Temperature Unit °C or °F

Push the button “MODE” (10) for longer to switch between the temperature unit °C (degrees Celsius and °F (degrees Fahrenheit).

f) Perform measurement

• Rinse the measuring probe with distilled water before the measurement and wipe it dry.
• Dip the tip of the measuring probe approx. 2 - 3 cm into the liquid to be measured.

Do not reach into the liquid with your hand or other body parts. This may cause injury, depending on liquid.

• Move the tip of the measuring probe back and forth slightly until the display of the measured value has stabilised. The automatic temperature compensation (“ATC”) ensures precise measured values even at different liquid temperatures.
• For the measured value to stay in the display when pulling the probe from the liquid, briefly push the button "H/M" (4). This activates the data hold function. Pressing the button "H/M" again deactivates the data hold function again.
• The combination meter also has a measuring mode for the maximum and minimum values.

Keep the button "H/M" (4) pushed for longer until the "MAX" (D) and "MIN" (F) flash in the display at the same time.

Now perform the measurement as described above. The combination meter saves the maximum and minimum value internally.

To display the saved maximum value, briefly push the button "H/M" (4). The display "MAX" (D) flashes.

To display the saved minimum value, briefly push the button "H/M" (4). The display "MIN" (F) flashes.

If you push the button "H/M" (4) again briefly, the display "MAX" (D) and "MIN" (F) flashes at the same time and you can continue measuring.

If the measuring mode for the maximum/minimum value is to be ended, keep the button "H/M" (4) pushed for a longer time until the display "MAX" and "MIN" disappears from the display.

While the combination meter is in the measuring mode for the maximum/minimum value, it cannot be switched off via the button “CAL” (5).

• The display shows dashes at the upper or lower edge (“____”) if the measured value exceeds or undercuts the permitted measuring range.
• Rinse the measuring probe with distilled water after each measurement and wipe it dry. This prevents a wrong measured value at the next measurement because the measuring probe still contains liquid residue from the preceding measurement.

g) End of operation

The pH electrode must always be kept moist to be able to deliver accurate measuring results for a long period of time. The same applies to the ORP electrode.

If a small amount of liquid is in the protective cap of the pH electrode at delivery because of this, this is normal. If no liquid is visible, you need to fill it into the protective cap after initial commissioning.

For this, add a little bit of the enclosed storage solution into the protective cap and screw the protective cap onto the pH-electrode. The pH electrode must not dry out anymore after initial commissioning.

The same applies to the ORP electrode (not enclosed, can be ordered as an accessory).

Observe that the protective flap with the storage solution in it does not tip over. If this has happened, wipe off the liquid with an absorbent cloth and put the cloth into the regular household waste. Wash your hands with water and soap carefully.

It is not necessary to calibrate the combination meter before each measurement. It is recommended to perform a calibration before every tenth measurement or every two weeks. If the enclosed buffer/calibration solutions are used up, you can purchase more as an accessory.

a) Measuring probe for the pH-value

• Insert the measuring probe into the combination meter if you have not done so yet. Switch on the combination meter The operating mode "PH" must be displayed now.
• Carefully rinse the tip of the measuring probe with distilled water to remove the liquid residue of the preceding measurements. Wipe the measuring probe dry.
• Put the measuring probe into the buffer solution with pH value 7, so that the tip of the measuring probe submerses by about 2 - 3 cm. Move the tip of the measuring probe back and forth in the buffer solution a bit.

Wait for at least 30 seconds until the display of the measured value in the display stabilises a little.

- Keep the button “☐/CAL” (5) pushed (approx. 3 seconds), until “CAL” (C) appears at the bottom of the display and the value “7.00” flashes in the display (or a value according to the liquid temperature; see print on the buffer solution).

Calibration starts now.

A brief push of the button “☐/CAL” (5) interrupts calibration prematurely.

• When calibration is completed, the display shows “SA” (“Save”) and then “End”; then the display shows the measured pH value.
• Pull the measuring probe from the buffer solution. Rinse the tip of the measuring probe with distilled water and wipe it dry.
• Put the measuring probe into the buffer solution with pH value 4, so that the tip of the measuring probe submerses by about 2 - 3 cm. Move the tip of the measuring probe back and forth in the buffer solution a bit.

Wait for at least 30 seconds until the display of the measured value in the display stabilises a little.

- Keep the button "CAL" (5) pushed (approx. 3 seconds), until "CAL" (C) appears at the bottom of the display and the value "7.00" flashes in the display (or a value according to the liquid temperature; see print on the buffer solution).

Calibration starts now.

A brief push of the button “CAL” (5) interrupts calibration prematurely.

- When calibration has been completed, the display shows “%” and the PTS-value (“percentage of slope”) for the electrode. For a value below 70% or above 130%, the measuring probe must be replaced. A value of 100% is best.

Then “SA” (“Save”) and “End” appear, then the display shows the measured pH value.

The display “SA” does not appear if calibration fails. In this case, pull the measuring probe from the buffer solution and rinse the tip of the measuring probe carefully with distilled water. Wipe the measuring probe dry.

Then perform another calibration, check if the tip of the measuring probe has actually been fully submersed in the buffer solution.

Always perform a calibration with the buffer solution with pH value 7 first and only then with the buffer solution with pH-value 4 (or alternatively with a buffer solution with pH value 10, which is not enclosed).

Buffer solutions with any other pH values than pH 4, pH 7 and pH 10 cannot be used for calibrating the combination meter.

b) Measuring probe for conductivity

• Insert the measuring probe for conductivity into the combination meter if you have not done so yet. Switch on the combination meter The operating mode “COND” must be displayed now.
• Carefully rinse the tip of the measuring probe with distilled water to remove the liquid residue of the preceding measurements. Wipe the measuring probe dry.
• Put the measuring probe into the calibration solution (1413 S/cm), so that the tip of the measuring probe submerses by about 2 - 3 cm. Move the tip of the measuring probe back and forth in the calibration solution a bit.

Wait for at least 30 seconds until the display of the measured value in the display stabilises a little.

- Keep the button "CAL" (5) pushed (approx. 3 seconds), until "CAL" (C) appears at the bottom and the display "1413 S/cm" flashes in the display.

Calibration starts now.

→ A brief push of the button “CAL” (5) interrupts calibration prematurely.
- When calibration is completed, the display shows “SA” (“Save”) and then “End”; then the display shows the measured conductivity.

The display “SA” does not appear if calibration fails. In this case, pull the measuring probe from the calibration solution and rinse the tip of the measuring probe with distilled water carefully. Wipe the measuring probe dry.

Then perform another calibration, check if the tip of the measuring probe has actually been fully submersed in the buffer solution.

For a measurement in liquids with very high conductivity, use a calibration solution with 12.88 mS/cm (not enclosed).

Calibration solutions with a different conductivity than 1413 S/cm or 12.88 mS/cm cannot be used for calibrating the combination meter.

- If the tip of the measuring probe is not submersed into a liquid and if the display does not show a measured value of 0 μS/cm, start calibration. Keep the button “☐/CAL” (5) pushed (approx. 3 seconds), as described above until “CAL” (C) appears at the bottom and the display “0 μS/cm” flashes in the display.

When calibration is completed, the display shows “SA” (“Save”) and then “End”; then the display shows the measured conductivity (this should now be 0 S/cm).

12. MAINTENANCE AND CLEANING

The product requires no servicing apart from replacing the rechargeable battery and cleaning of the measuring probes. Do not disassemble the product (except for the work described in these operating instructions, such as for exchanging the measuring probes).

Clean the product with care, e.g. with a soft, clean cloth. Do not push on the display too much; this will not only cause scratches but may also damage the display.

Only use distilled water (or deionised water) to clean the tips of the measuring probes, since the measured values may otherwise be influenced. Use only paper tissues to dab dry/dry the measuring probes.
