Proceed as follows to switch the device on:
- Switch on the meter.
- Hold down the "AC/DC" button (8) for approx. 2s. The display reads "PoFF".
- Select the desired mode with the "UNIT" (1) or "AC/DC" button (8).

"HOLD" disappears

Switching the Device On and Off

Switch the device on using the POWER key (3). After a brief initialisation phase, the meter is ready for
operation. To turn off press the "POWER" button (3) again. The "OFF" display appears and the display
shuts down with a beep tone. Always switch off the meter once you have completed measurement.

Carrying out a Measurement

The highly sensitive sensor always shows a low value in normal operation.
This value corresponds to the earth's magnetic field and can be compensated
via the zeroing function.
Both DC and DC fields can be measured with the meter. The measuring mode must be correspond-
ingly adjusted. When the device is switched on it is preset to the DC mode.
Every movement of the sensor can lead to a deviation in the measured value. Before
beginning the measurement, move the sensor close to the object to be tested and
then switch the meter on.

Zeroing (relative measurement)

The high-sensitivity sensor already display the natural earth's magnetic field is displayed. In order to not
include this value in the measured value, the display can be reset to zero.
For this purpose, proceed as follows:
- Switch on the meter.
