Frequently Asked Questions - MultiMeterHome Laserliner

How to measure DC voltage?

Set the rotary switch to the appropriate V--- range (12 V to 300 V). Connect the test leads (black to ground, red to potential) and read scale B.

How to measure AC voltage?

Set the rotary switch to the appropriate V~ range (60 V to 300 V). Connect the test leads and read scale B.

What to do if the needle does not zero before a measurement?

Use the rotary knob (2) to adjust zero on the V.mA = scale or knob (3) for the OHM scale (by short-circuiting the probes). If adjustment is impossible, replace the battery.

How to replace the fuse?

Disconnect all test leads. Open the housing by unscrewing the screws on the back. Replace the defective fuse with a F 630 mA / 300 V fuse (∅5x20 mm). Close carefully.

How to replace the battery?

Disconnect the test leads. Open the housing. Replace the 1.5 V AAA battery, respecting polarity. Close the housing.

What safety precautions to take?

Do not exceed 300 V in CAT III. Use the device only in suitable weather conditions. Do not touch bare test leads. Check for absence of voltage before changing function.

What is the meaning of CAT III?

CAT III (overvoltage category III) means the device is suitable for measurements on fixed installations (electrical panels, circuit breakers) with a maximum voltage of 300 V to ground.

Can I measure currents above 600 mA?

No, the maximum measurable current is 600 mA. Beyond that, the internal fuse will blow. Use a clamp meter for higher currents.

How to interpret the dial for battery test?

The three-color dial indicates battery status: green (good), orange (weak), red (replace). Set the switch to BAT. and connect the probes to the battery terminals.

What to do if the device does not work?

Test the device by connecting it to known voltage sources (e.g. a 230 V socket in the case of AC testing or a car battery in the case of DC testing).

- The device must no longer be used if one or more of its functions fail or the battery charge is weak.

- The device must be disconnected from all power sources and measuring circuits before opening the cover to change the battery(ies) or fuse(s). Do not switch on the device with the cover open.

- Observe the safety precautions of local and national authorities relating to the correct use of the device and any prescribed safety equipment (e.g. electrician's safety gloves).

- If you have to take hold of the measuring spikes, do so by the grip sections only. Do not touch the measuring contacts whilst the measurement is being taken.

- Make sure that you always select the correct connections and rotary switch position with the correct measuring range for the measurement to be carried out.

- Do not work alone in the vicinity of hazardous electrical installations and only under the guidance of a qualified electrician.

- Disconnect the power supply to the electrical circuit before measuring or checking the diodes, resistance or battery charge. Make sure that all high-voltage capacitors are discharged.

To check, remove the measuring leads of the device from the test piece before changing the mode.

- Check that all high-voltage capacitors are discharged.

- When connecting to a voltage, always connect the black measuring lead first before the red lead. Follow the reverse procedure when disconnecting.

1 replacing the battery / fuse

To replace the battery or fuse, first disconnect the test prods from all voltage sources. Undo all the screws at the rear of the device and replace the battery or replace the defective fuse by a fuse of the same type and rating. Do not touch the green pc-board. Also make sure it is kept clean. Close the housing and carefully screw the meter back together. Do not switch on the device with the cover open.

Be sure to pay attention to polarity.

1 1 x 1.5 V type AAA

2 F 630 mA / 300 V (∅ 5 mm x 20 mm)

Turn the rotary switch to position "Ω". Hold the two test prods so that they touch and with rotary knob (3) adjust the pointer exactly to "0" on the OHM-scale (A). If this is not possible, the battery needs to be replaced.

Notes on measurement

Before each measurement, check that the pointer is set exactly to „0“ on the V.mA== / -scale (B/C). If not, adjust the pointer with rotary knob (2).

If the value of the measured variable is not known in advance, set the rotary switch to the highest measuring range.

Then reduce the measuring range step by step until a satisfactory resolution is achieved.

If the pointer remains to the left of the "0" during the measurement or to the right of the "0" when measuring resistance, either the test prods are mixed up or the measuring circuit is interrupted. Repeat the measurement with the test prods changed over.

The measuring range is exceeded if the pointer remains to the right of "300" ("60" / "12") or to the left of "1 kΩ" when measuring resistance. Repeat the measurement with a higher measuring range.
