Operation Manual

GMC-I Messtechnik GmbH 15
3 Initial Start-Up
The MERISO PRIME+ test instrument is supplied with a base
which serves as a compartment for storing test cables, the guard
cable (feature G1), the test probes and the battery pack
(feature C1).
Attention!
!
The test instrument may only be operated if the
base is properly attached and secured.
3.1 Battery Operation, Feature C1 (not with B1/B2)
The battery pack is required for operation of the MERISO
PRIME+ without mains power. The battery back includes 8 NiMH
batteries. No other battery packs may be used.
The battery pack is charged automatically by the integrated mains
power pack. Optional use of an automotive charging adapter is
also possible. The device must be switched on in this case (any
switch position other than OFF).
Attention!
!
If only the batteries are to be charged (instrument is
ready for operation in SETUP position), please ensure
that the test instrument cannot be used by unauthorized
personnel during the charging process.
3.1.1 Removing the Device Base and Inserting or Replacing
the Battery Pack
Please observe instructions included in this chapter if the device
