GMC-I Messtechnik GmbH 17
Attention!
!
Use only the screws furnished with the device together
with washers. Longer screws may reduce creepage dis-
tances or damage the device.
If a battery pack (feature C1) has been installed and the device is
not connected to the mains, the battery symbol appears at
the display when the device is switched on, and the number of
dark bars displayed in the symbol indicates the battery charge
level.
After installing the battery pack, the device is automatically sup-
plied with power from the batteries.
3.2 Initial Start-Up with Feature B1/B2
3.2.1 Retrofitting Feature B1/B2
Retrofitting with a high-voltage module (feature B1 or B2) can only
be performed by GMC-I Service GmbH.
The MERISO PRIME+ serves to determine the insulation value in
a non-destructive manner. If it is too low, it is possible to detect
the weak point with the high-voltage module (B1 or B2).
3.2.2 Key Switch (feature B1 or B2)
The key switch prevents unauthorized start-up of the high-voltage
module. Keep the key in a safe place which can only be accessed
by authorized personnel.
Torn the key to the “0” position and remove after each test has
been completed.
Note
When the key is removed or the high-voltage module
is turned off, the menu functions for the high-voltage
module cannot be accessed at the
MERISO PRIME+!

Pinching!
