12.4 Fuses
Take care of the safety instructions as given at the beginning of this manual
while working at and inside the instruments!
Working inside the instruments is subject to briefed personnel familiar with
potential risks!
In case of exchanging fuses the customer has to be certain that fuses of
specified type and rated current are used. It is prohibited to use repaired
fuses or defective fuse holders or to short-circuit fuse carriers (fire haz-
ard).
After visual checking, check the fuses with an ohmmeter.
If low impedance has been measured, the fuse is in order.
High impedance means, the fuse is out of order and must be replaced.
