General information
The operator should not neglect to carefully read the following
instructions and those of the mainframe HM 8001, to avoid any
operating errors and to be fully acquainted with the module
when later in use.
After unpacking the module, check for any mechanical damage
or loose parts inside. Should there be any transportation dam-
age, inform the supplier immediately and do not put the module
into operation.
This plug-in module is primarily intented for use in conjunction
with the Mainframe HM 8001. When incorporating it into other
systems, the module should only be operated with the specified
supply voltages.
Safety
Every module is manufactured and tested for use only with the
mainframe HM8001 according to IEC 348 Part 1 and 1a (Safety
requirements for electronic test and measurement equipment).
All case and chassis parts are connected to the safety earth con-
ductor. Corresponding to Safety Class 1 regulations (three-con-
ductor AC power cable). Without an isolating transformer, the
instrument's power cable must be plugged into an approved
three-contact electrical outlet, which meets International Elec-
trotechnical Commission (IEC) safety standards.
Warning!
Any interruption of the protective conductor inside or out-
side the instrument or disconnection of the protective
earth terminal is likely to make the instrument dangerous.
Intentional interruption is prohibited.
The istrument must be disconnected and secured against unin-
tentional operation if there is any suggestion that safe operation
is not possible. This may occur:
— if the instrument has visible damage,
— if the instrument has loose parts.
— if the instrument does not function,
— after long storage under unfavourable circumstances (e.g.
outdoors or in moist environments),
— after excessive transportation
packaging).
stress (e.g. in poor
When removing or replacing the metal case, the instrument
must be completely disconnected from the mains supply. H any
measurement or calibration procedures are unavoidable on the
opened-up instrument, these must only be carried out by qual-
ified personnel acquainted with the danger involved.

Operating conditions
The ambient temperature range during operation should be
between +10°C and +40°C and should not exceed —40°C or
+70°C during transport or storage. The operational position is
optional, however, the ventilation holes on the HM8001 and on
the plug-in modules must not be obstructed.
Warranty
Before being shipped, each plug-in module must pass a 24 hour
quality control test.
Provided the instrument has not undergone any modifications
Hameg warrants that all products of its own manufacture con-
form to Hameg specifications and are free from defects in mate-
rialand workmanship when used under normal operating condi-
tions and with the service conditions for wich they were fur-
nished.

without charge, any such product which in Hameg's sole opin-
ion proves to be defective with the scope of this warranty.
This is Hameg's sole warranty with respect to the products deli-
vered hereunder. No statement, representation, agreement or
understanding, oral or written, made by an agent, distributor,
representative or employee of, which is not contained in thiss
warranty will be binding upon Hameg, unless made in writing

for a particular use which exceed the aforestated obligation are
hereby disclaimed by Hameg be liable to buyer, in contract or in
tort, for any special, indirect, incidental or consequential dam-
ages, espresses, losses or delays however caused.
In case of any complaint, attach a tag to the instrument with a
description of the fault observed. Please supply name and
department, address and telephone number to ensure rapid ser-
vice.
The instrument should be returned in its original packaging for
maximum protection. We regret that transportation damage
due to poor packaging is not covered by this warranty.
Maintenance
The most important characteristics of the instruments should
be periodically checked according th 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.
Remove both screws on rear pane! 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
HM 8001 Mainframe were followed — especially for the selec-
tion of the correct mains voltage — start of operation consists
practically of inserting the module into the right or left opening
of the mainframe. The following precautions 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 HM 8001 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 HM 8001 set must be turned on and in full operat-
ing 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 exchang-
ing a module, the instrument must be disconnected from the
test circuit.
