If you later want to replace the engineering unit (3), you insert a screw-
driver into the lateral slot in the front panel and turn (be careful!) the
screwdriver as shown until the front panel has been completely
removed. Replace the engineering unit.
You can find the panel cutout and the mechanical dimensions in chapter
7.3 Mechanical Dimensions.
3.3 Rated Operational Voltage
Before you switch on the instrument, make sure that the supply voltage
corresponds to the rated operational voltage indicated on the power
supply module.
3.4 Jumper Setting on Modules
As some modules are designed to cover several ranges it can be neces-
sary for you to select the required range by moving an internal jumper.
The major part of the input modules, the excitation output module and
the analogue output module have this possibility for range selection. On
the following pages the jumper setting is shown for the modules:
3.4.1 Voltmeters
3.4.2 Ammeters
3.4.3 Ohmmeters
3.4.4 Frequency - and tachometers
3.4.5 Dupline

Analink Interface module
3.4.6 Output modules
Note! Always remember to turn off the power supply before you plug in
or pull out the modules.

Caution!!
Since the input circuitry is not galvanically
isolated, the potential of the measured
variable will be present on all connections
to the unit (i.e. “HOLD” input). This is im-
portant specially when you are measuring
line voltage and current.
