Maintenance

The most important characteristics of the
instruments should be periodically checked
according to the instructions provided in the
sections "Operational check and "Alignment
procedcure. To obtain the normal operating
temperature, the mainframe with inserted module
should be turned on at least 60 minutes before
starting the test. The specified alignment
procedure should be strictly observed. When
removing the case detach mains/line cord and any
other connected cables from case of the
mainframe HM8001-2. Remove both screws on
rear panel and, holding case firmly in place, pull
chassis forward out of case. When later replacing
the case, care should be taken to ensure that it
properly fits under the edges of the front and rear
frames. After removal of the two screws at the rear
of the module, both chassis covers can be lifted.
When reclosing the module, care should be taken
that the guides engage correctly with the front
chassis.

Operation of the module

Provided that all hints given in the operating
instructions of the HM8001-2 Mainframe were
followed especially for the selection of the correct
I m p o r t a n t h i n t s
mains voltage start of operation consists prac-
tically of inserting the module into the right or left
opening of the mainframe. The following pre-
cautions should be observed:
Before exchanging the module, the mainframe
must be switched off. A small circle (o) is now
revealed on the red power button in the front
centre of the mainframe.
If the BNC sockets at the rear panel of the HM8001-
2 unit were in use before, the BNC cables should
be disconnected from the basic unit for safety
reasons. Slide in the new module until the end
position is reached.
Before being locked in place, the cabinet of the
instrument is not connected to the protective earth
terminal (banana plug above the mainframe
multipoint connector). In this case, no test signal
must be applied to the input terminals of the
module.
Generally, the HM8001-2 set must be turned on
and in full operating condition, before applying any
test signal. If a failure of the measuring equipment
is detected, no further measurements should be
performed. Before switching off the unit or
exchanging a module, the instrument must be
disconnected from the test circuit.
