BRUEL & KJAER 1617 - Operation; Preliminary Adjustments

3. OPERATION
3.1. PRELIMINARY ADJUSTMENTS
Before connecting a mains supply the following checks and adjustments should be car-
ried
out to ensure safe operation of the apparatus.
3 . 1.1. Selection of Line Voltage
The instrument can be operated on single phase AC line voltage from 100 V to 240 V,
with a tolerance of ± 10% , at frequencies between 50 and 400 Hz.
Set the LINE VOLTAGE SELECTOR to the voltage to be used by turning it with a small
coin or a broad-bladed screwdriver .
3.1.2. Fuse Rating
For operation on 100, 115 and 127 V, two 0,2 A fuses (VF 0012) are required, one in
each
holder . Operation with 200, 220 and 240 V requires only one 0,2 A fuse, and
when these voltages are selected as described in 3 .1. 1, the left-hand fuse is electrically
by-passed.
Make sure that only fuses with the required rated current and of the specified type are
used
for replacement. The use of mended fuses and the short-circuiting of fuse holders
shall be avoided.
