densation water could damage your device. Allow the device
to come to room temperature before switching it on.

5.1 Settings
Before the panelmeter is installed, the decimal point and the
unit of measurement must be set, depending on the voltage
measuring range. To do this, proceed as follows:
a) Open the panel housing by carefully unscrewing the four
fixing screws with a suitable crosshead screwdriver.
b) Remove the rear housing shell.
c) The measuring board is now exposed. Remove this from the
mounting (pin socket at the front).
d) The jumpers are now accessible. In the following tables the
"pin contact pairs" are shown from left to right.
e) In order to set the decimal point, observe the following
table:
Decimal point position Jumper JP2
0000 -
000.0 -
00.00 -
0.000 -
Where: "-" = not used; "0" = no jumper; "S" = jumper, i.e. two
pins bridged
f) When the decimal point has been set, the unit of measure-
ment must be set . Note the following table:
- - 0 0 0
- - 0 0 S
- - 0 S 0
- - S 0 0
