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.
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
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.

button. The light switches itself off automatically as soon as the
button is released.
Automatic fuse
10
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.
Calibration
11
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.
