Step Description
7
Select the type of power supply currently applicable to the mobile unit (see also
section 7.2.2).
If it is not a ‘true’ mains voltage (e.g. when using an emergency power
unit), Battery powered must be selected.
Result: The mobile unit runs through several tests and operating steps which
must be completed before the actual phase identification:
• Test for the mains power supply (mains operation only)
• Test for GPS reception
• Establishing a GSM connection to the base station
• Data synchronisation with the base station
After successful completion of the procedure, you are automatically forwarded
to the measurement screen (see also page 7.3).
If a test or a work step could not be carried out successfully, correct the cause
of the problem and repeat the procedure from step 3 .
If the mobile unit is mains powered, the local mains supply voltage serves
as the reference phase during the actual measurement (see also section
7.2.1). The mains voltage may not be disconnected! The GSM connection
ends upon the start of the measurement.

If you are tapping the measured voltage using the high voltage sensor, move it
to the conductor as described in section 7.2.2.3.
9 Read the phase from the measurement screen (see page 7.3) or interpret the
results according to the audible / visual signals of the HV sensor.
10 Stop the measurement with the Stop button.
11 If you want to save the measurement data, insert a USB flash drive into the
USB port
and touch on the
Store measurement
button.
This button is only available, if the saving of measurement data is enabled in
the device settings (see section 7.1).
