It features True RMS measurement to ensure accurate measuring results even in case of non-sinusoidal or dis- torted signal waveforms. Due to its weather- proof housing (IP 67 protection), it is suited for outdoor applications. The meter will measure voltages up to 1000 V /~, currents up to 10 A /~, frequen- cies up to 10 MHz, resistances up to 40 MΩ, capacitances up to 40 mF and temperatures from

20 °C to +760 °C. It will also test diodes. A buzzer is provided for testing the continuity, 4 Attaching the Label Attention labels in eight lang- uages are supplied with the meter. Prior to operation, at- tach the corresponding label in your language to the field provided on the battery com- partment! 5 Operation

1) To switch on the meter, set the selector

switch (10) from the position “OFF” to the desired function. If there is no indication on the display (6) or if the symbol appears, in- sert a new battery (

2) To provide a more comfortable reading posi-

tion, unfold the tilt stand on the rear side of the meter, if required.

3) Press the button (9) to switch on and off

the display illumination.

4) After operation, set the selector switch to

“OFF”. The meter will also be switched off automatically if it is not used for approx. 30 minutes. Before switching off automati- cally, warning signals will sound (two short beeps three times in succession followed by a long beep). To switch it on again, press a button or turn the selector switch. If the meter is to be put out of opera- tion definitively, take it to a local recy- cling plant for a disposal which is not harmful to the environment. WARNING With this meter, dangerous volt- ages can be measured. Particu- lar attention should be paid when measuring voltages equal to or higher than 42 V!

1. Wear protective gloves to protect yourself

against electric shock.

2. When applying the test tips, make sure

that your fingers will be protected behind the collars of the tips.

3. Never perform any measurements when

the meter or the test leads are damaged. Always replace damaged test leads by original test leads.

GBIf the meter is not used for a longer pe- riod, it is recommended to remove the bat- tery to prevent any damage to the meter due to battery leakage.

5.1 Connecting the test leads

The meter is supplied with two test leads (red and black). They will allow to perform all meas- urements except for temperature measure- ments (

1. The jack “COM” (12) is the common (

) jack for all measurements. Connect the black test lead to this jack.

2. The jack “V Hz Ω CAP °C °F” (11) is the

common (+) jack for all measurements, ex- cept for measuring currents. Connect the red test lead to this jack.

3. For measuring currents up to 400 mA, con-

nect the red test lead to the jack “µA / mA” (5).

4. For measuring currents between 400 mA

and 10 A, connect the red test lead to the jack “10A” (4). For measuring, remove the protective caps from the test tips and replace them after use. IMPORTANT! To ensure protection of the meter according to IP 67 (e. g. to protect it against humidity for outdoor applications), in- sert the sleeves (13) provided into the two red jacks not used. 6 Measuring Caution: Before switching to another measur- ing function, always remove the test tips from the object to be measured to prevent damage to the meter!

6.1 Measuring voltages

Caution: Connect the red test lead to the jack “V Hz Ω CAP °C °F” (11). If it is connected to the jack “10A” (4) or “µA/mA” (5), the meter and the object to be measured may be dam- aged!

1) Set the selector switch (10) to the position

“V ” to activate the mode “DC voltage measurement” (“DC” will be displayed).

2) For AC voltage measurements, press the

button “MODE” (3) [“AC” will be displayed]. To return to “DC”, press the button “MODE” again.

3) Apply the test tips to the object to be meas-

ured and read the value on the display. If the red test tip is applied to the negative pole and the black tip to the positive pole when measuring DC voltages, there will be a minus sign in front of the value displayed.

6.2 Measuring currents

The current to be measured must not ex- ceed 10 A!

1) For measurements up to 400 mA, connect

the red test lead to the jack “µA/mA” (5); for measurements up to 10 A, connect it to the jack “10A” (4). With unknown currents, start with the 10 A range to be on the safe side.

2) According to the intensity of current, set the

selector switch (10) to the following position: up to 4000 µA position “µA” > 4000 µA to 400 mA position “mA ” > 400 mA to 10 A position “10A ” The mode “DC current measurement” will be activated (“DC” will be displayed).

3) For AC current measurements, press the

button “MODE” (3) [“AC” will be displayed]. WARNING Take into account unexpected voltages on objects to be meas- ured. Capacitors, for example, may be dangerously charged even if the voltage source has been switched off.

Never use this meter for measuring circuits with corona discharges (high voltage). Risk of electrocution!

The maximum voltage to be measured must not exceed 1000 V¿ /~, otherwise you will risk your life! WARNING Measurements in circuits carry- ing more than 42 V must only be made by persons able to recog- nize a hazard of contact and to take the required safety precau- tions. In case of measurements with a hazard of contact, avoid working on your own. Ask a sec- ond person to assist.

GBTo return to “DC”, press the button “MODE” again.

4) Insert the meter via the test leads into the

circuit to be measured and read the value on the display. If the red test tip is applied to the negative pole and the black tip to the posi- tive pole when measuring DC currents, there will be a minus sign in front of the value displayed. If the current measured exceeds the ad- missible value of a measuring range, warn- ing signals will sound and “OL” (overload) will be displayed. In this case, select the next higher range.

6.3 Measuring resistances

Never measure a resistor when voltage is applied; always measure it separately, otherwise the measurement will be inaccu- rate. For this purpose, it may be necessary to solder it out of the circuit.

1) Set the selector switch (10) to the position

“Ω ” to activate the mode “resistance measurement”.

2) Apply the test tips to the resistor and read

the value on the display. As long as the re- sistance value between the test tips is > 40 MΩ, “OL” will be displayed to indicate that the measuring range has been ex- ceeded.

6.4 Testing the continuity

Never test the continuity when voltage is ap- plied, otherwise the measurement will be in- accurate. The continuity buzzer will help to detect inter- ruptions in the circuit.

1) Set the selector switch (10) to the position

“Ω ” to activate the mode “resistance measurement”.

3) Apply the test tips to the measuring points. If

the resistance value between the points is smaller than 35 Ω, the internal buzzer will sound. The resistance value will be dis- played up to 400 Ω. With higher values, the overload indication “OL” will appear.

Never test a diode when voltage is applied; always test it separately, otherwise the measurement will be inaccurate. For this purpose, it may be necessary to solder the diode out of the circuit.

1) Set the selector switch (10) to the position

“Ω ” to activate the mode “resistance measurement”.

2) To switch to diode test, press the button

“MODE” (3) twice (diode symbol will be displayed).

3) Apply the black test tip to the cathode of the

diode and the red test tip to the anode. With a measurement current of approx. 1 mA, a forward voltage up to 1.999 V will be dis- played. If a value around 0 V is displayed, the diode has a short circuit. If “OL” is dis- played, the diode is interrupted, reverse- biased (reverse the polarity of the diode) or has a higher forward voltage (e. g. some LEDs).

6.6 Measuring capacitances

1) Set the selector switch (10) to the position

2) Apply the test tips to the capacitor. With

electrolytic capacitors, observe the polarity: Apply the red test tip to the positive pole, apply the black test tip to the negative pole. Read the value on the display. With very high capacitances, the measuring process will require some time. It may take a few minutes before the reading on the display has stabilized. When measuring capaci- tances, the bar graph will have no function. Note: If the display shows “diS.C”, the capaci- tor is charged and must be discharged before measuring. Due to the long discharge time, it is not recommended to discharge the capacitor via the multimeter. WARNING Never measure a capacitor when it is charged or when oper- ating voltage is applied; other- wise you will risk an electric shock. Switch off the power supply and discharge the capacitor before soldering it out of the cir- cuit.

GB6.7 Measuring frequencies

1) Set the selector switch (10) to the position

2) Apply the test tips to the measuring points

like for measuring voltages.

3) Read the frequency on the display.

6.8 Measuring temperatures

For measuring the surface temperature of ob- jects, the meter is supplied with a type K tem- perature sensor with banana adapter plug. The temperature measurement is not suitable for medical purposes!

1) Connect the sensor to the multimeter via the

adapter plug: Connect the positive pole to the jack “V Hz Ω CAP °C °F” (11) and the negative pole to the jack “COM” (12). To ensure protection of the meter accord- ing to IP 67 (e. g. to protect it against humid- ity for outdoor applications), insert the sleeves (13) provided into the two red jacks not used.

2) Set the selector switch (10) to the position

°F”. After switching on, the mode “Fahrenheit “ will be activated (“°F” will be displayed).

3) To switch to Celsius, press the button

“MODE” (3) [“°C” will be displayed]. To return to “°F”, press the button “MODE” again.

4) Apply the sensor to the object to be meas-

5) Once the reading has stabilized (after ap-

prox. 30 seconds), read the temperature on the display. 7 Additional Functions

7.1 Manual range selection

The optimum range for a measuring function will always be selected automatically when “AUTO” is displayed.

1) To hold a range selected automatically,

press the button “RANGE” (1). “AUTO” will disappear and “MANU” will appear.

2) Each time the button “RANGE” is pressed,

the next higher range will be selected. This will reduce the resolution of the measured value, but it will prevent permanent switch- ing if the measured value fluctuates be- tween two ranges. When the highest possible range has been reached and the button is pressed again, the smallest range will be selected. If the range is too small, “OL” (overload) will be displayed. When measuring voltages and currents, warning signals will sound ad- ditionally.

3) To return to automatic range selection, keep

the button “RANGE” pressed for approx. 2 seconds until “AUTO” appears instead of “MANU”.

7.2 Data hold function

To hold a measured value on the display (e. g. to be able to read the value more easily when the test tips have been removed from the ob- ject to be measured), press the button “HOLD” (2). The digital display will hold the measured value, “HOLD” will appear and the automatic range selection will be deactivated (“MANU” will be displayed). To deactivate the data hold function, press the button “HOLD”. “HOLD” will disappear and the automatic range selection will be reacti- vated (“AUTO” will be displayed).

7.3 Indicating the maximum/

minimum value With the MAX/MIN function activated, the meter will record the maximum value and min- imum value of a measurement and indicate them on the display. To activate this function, press the button “MAX / MIN” (8). The automatic range selection will be deactivated (“MANU” will be displayed). The button “MAX/MIN” will allow to switch between three indications:

1. “MAX”: The digital display will show the

maximum value measured since the func- tion has been activated. If a higher value is reached while measuring, the indication will be updated accordingly.

2. “MIN”: The digital display will show the min-

imum value measured since the function has been activated. If a lower value is WARNING To avoid electric shock, do not apply the temperature sensor to any objects carrying voltage.

GBreached while measuring, the indication will be updated accordingly.

3. “MAX/MIN” (flashing): The digital display will

show the present reading. To deactivate this function, keep the button “MAX/MIN” pressed for approx. 2 seconds. The automatic range selection will be reacti- vated (“AUTO” will be displayed). To reset the values in order to perform a new MIN/MAX measurement, deactivate and reac- tivate the function.

7.4 Indicating short peaks

When measuring voltages (¿/~) and currents (¿/~), the PEAK function will allow to indicate peak values occurring too shortly to be recorded during the MAX/MIN measurement

It will be possible to measure peaks of a dura- tion ≥ 1 ms.

1) When measuring voltages or currents, wait

until the reading on the display has stabi- lized.

2) Keep the button “PEAK” (7) pressed until

“CAL.” is displayed: A calibration will be per- formed.

3) After calibrating, press the button “PEAK”.

The digital display will indicate the positive peak value of the measurement (“P MAX”). The automatic range selection will be deac- tivated (“MANU” will be displayed). When the button “PEAK” is pressed again, the indication will change to the neg- ative peak value of the measurement (“P MIN”). If a higher or lower peak value is reached while measuring, the corresponding indica- tion will be updated.

4) Use the button “PEAK” to switch between

5) To deactivate this function, keep the button

pressed for approx. 2 seconds until “P MAX” or “PMIN” disappears. The automatic range selection will be reactivated (“AUTO” will be displayed). Note: If you select another measuring function with the selector switch (10) after calibrating, repeat the calibration for the new measuring function. 8 Inserting a New Battery or Replacing Fuses
