2.4 Mains connection
Follow the instructions below for connecting to the power supply. If
the instrument is operated with a mains voltage set wrongly and/or
wrong mains fuse, there is a danger of fire!
2.4.1 Setting the mains voltage
Before switching on the 732 IC Detector for the first time, check that the
mains voltage set on the instrument (see Fig. 8) matches the local
mains voltage. If this is not the case, you must reset the mains voltage
on the instrument as follows:
1 Disconnect mains cable
Disconnect mains cable from mains connection plug 18 18 of the
732 IC Detector.
2 Remove fuse holder
Using a screwdriver, loosen fuse holder 19 19 below the mains
connection plug 18 18 and take out completely.
3 Check and change fuse if necessary
Carefully take the fuse installed for the desired mains voltage out
of fuse holder 19 19 and check its specifications (the position of the
fuse in the fuse holder is marked by the white arrow imprinted
next to the mains voltage range):
100 … …120 V 0.63 A (slow-blow) Metrohm No. U.600.0014
220 … …240 V 0.315 A (slow-blow) Metrohm No. U.600.0011
4 Insert fuse
Change fuse if necessary and reinsert in fuse holder 19 19.
5 Install fuse holder
Depending on the desired mains voltage, insert fuse holder 19 19 in
the 732 IC Detector so that the corresponding mains voltage
range can be read normally and the adjacent white arrow points
to the white bar imprinted below the fuse holder (see Fig. 8).
