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
I m p o r t a n t h i n t s
followed especially for the selection of the
correct 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.
