Frequently Asked Questions - MultiMeterPocket Laserliner

How to replace the batteries of the MultiMeterPocket?

Open the battery compartment cover on the back of the device. Insert two AAA (LR03) batteries respecting the indicated polarity. Close the cover. Be sure to remove the batteries if not used for an extended period.

What are the voltage measurement ranges?

DC voltage: 200 mV, 2 V, 20 V, 200 V and 600 V. AC voltage: 2 V, 20 V, 200 V and 600 V. Range selection is automatic.

How to use the non-contact voltage detector?

Place the sensor (near the tip of the device) 5-10 mm from a conductor or socket. If an AC voltage from 100 V to 600 V is present, the display lights up. This tool does not replace a two-pole test.

Why does the multimeter not turn on?

First check the battery condition. Replace if necessary. Make sure the rotary switch is not set to 'OFF'. If the problem persists, the internal fuse may have tripped (see manual).

What does the 'O.L' display mean?

'O.L' stands for 'Open Line' or 'Overload'. It indicates that the measurement circuit is not closed (open) or that the measured value exceeds the selected range.

How to test a diode with this device?

Set the switch to 'Ω' then press 'Mode' once to select diode test. Connect the leads: red to anode, black to cathode. The forward voltage is displayed (approx. 0.5-0.8 V). If 'O.L' is displayed, reverse the leads (blocking).

Does the continuity test work with the device off?

No, the device must be on and the switch set to 'Ω'. Press 'Mode' twice to activate continuity test. An audible signal sounds for resistance below 150 Ω.

How to disable the auto power off function?

The auto power off cannot be disabled. The device turns off after 15 minutes of inactivity. To turn it back on, turn the rotary switch to 'OFF' and then back to the desired function.

What is the accuracy of current measurements?

DC current: ±2.0% of reading + 8 digits. AC current: ±2.5% of reading + 10 digits. Ranges go from 200 µA to 200 mA. Do not exceed 200 mA, otherwise the internal fuse will trip.

Is it possible to measure voltages above 600 V?

No, the maximum allowed voltage is 600 V AC/DC. The overvoltage category is CAT III 1000 V, but this concerns protection against transients, not continuous measurement. Never exceed 600 V.

B V≈ Voltage measurement DC/AC

redblack

To take a voltage measurement, turn the rotary switch to position „V“ and press the „Mode“ button to set the voltage mode (AC, DC).

Then connect the measuring contacts to the object to be tested. The measured value acquired and the polarity appear on the display.

4 Ω Resistance measurement

To measure the resistance, turn the rotary switch to position „Ω“. Then connect the measuring contacts to the object to be tested. The measured value acquired appears on the display. If „O.L.“ appears on the display instead of a measured value, either the measuring range has been exceeded or the measuring circuit is not closed or has been interrupted. Resistances can only be measured correctly in isolation; therefore, the components might need to be disconnected from the remainder of the circuit.

When measuring resistance, to avoid the risk of the results of a measurement being distorted, there must be no traces of dirt, oil, solder spray or other contamination on the test prods.

5 Continuity test

MultiMeter-Pocket

To test continuity, turn the rotary switch to position „Ω“ and press the „Mode“ switch twice to activate the „Continuity test“ function. Then connect the measuring contacts to the object to be tested. A measured value of < 150 ohms is recognised as continuity; this is confirmed by an audible signal. If „O.L.“ appears on the display instead of a measured value, either the measuring range has been exceeded or the measuring circuit is not closed or has been interrupted.

6 Diode test

Reverse direction Forward direction

To test the diode, turn the rotary switch to position „Ω“ and press the „Mode“ switch once to activate the „Diode test“ function. Then connect the measuring contacts to the diode. The measured value acquired appears on the display. If „O.L.“ appears on the display instead of a measured value, the diode has either been tested in the reverse direction or is faulty.

7 μA mA Current measurement DC/AC

To take a current measurement in the range from 0 to 200 mA, turn the rotary switch to position „mA“ and press the „Mode“ button to set the voltage mode (AC, DC). To take a current measurement in the range from 0 to 200 μA, turn the rotary switch to position „μA“ and press the „Mode“ button to set the voltage mode (AC, DC).

Laserliner

Disconnect the circuit before connecting the meter. Then connect the measuring contacts to the object to be tested. The measured value acquired and the polarity appear on the display. Disconnect the circuit again before disconnecting the meter.

No currents above 200 mA may be measured in the A/mA range! Currents above this level trigger the automatic fuse in the meter.

8 Voltage detection, non-contact (AC warning)

Fig. H: The non-contact voltage detector integrated in the meter is able to detect AC voltages from 100 V to 600 V. Even when the device is switched off, live cables or cable breaks still have to be reckoned with. Run the voltage sensor along the object to be tested (5 - 10 mm). The display lights up if AC voltage is detected.

Non-contact voltage detection is no substitute for conventional voltage testing. As the device detects an electrical field, it will react even to static charge.

Voltage detection, single-pole phase test

Connect the red test prod to the phase or neutral conductor. The red LED only lights up if the phase conductor is live. This function also works if the device is switched off. When the single-pole phase test is carried out on the outer conductor, the indicator function may be adversely affected under certain conditions (e.g. when insulating personnel protective equipment is used or at insulated locations).

The single-pole phase test is not suitable for checking for zero voltage. To do this, you need to carry out a two-pole phase test.

9 Flashlight function

To switch on the flashlight, press and hold down the corresponding button. The light switches itself off automatically as soon as the button is released.

10 Automatic fuse

The meter is equipped with an electronic auto-reset fuse in all ranges and can intercept switching errors under normal operating conditions. If the electronic fuse trips, de-energise the electrical circuit and disconnect the meter. Rectify the switching error. The device will resume normal operation when restarted.

11 Calibration

The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.
