Operating Conditions; Operation Of The Module - Hameg Instruments Hm 8042 Bedienungsanleitung

General information
The operator should not neglect to carefully read the following
instructions and those of the mainframe HM8001, 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 damage, 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 HM8001. 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 conductor. Corresponding to Safety Class 1
regulations (three-conductor AC power cable). Without an
isolating transformer, the instruments power cable must be
plugged into an approved three-contact electrical outlet,
which meets International Electrotechnical Commission
(IEC) safety standards.
Warning!
Any interruption of the protective conductor inside or
outside the instrument or disconnection of the protective
earth terminal is likely to make the instrument
dangerous. Intentional interruption is prohibited.
The tstrument must be disconnected and secured against
unintentional 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 stress (e.g. in poor
packaging).
When removing or replacing the metal case, the instrument
must be completely disconnected from the mains supply. If
any measurement or calibration procedures are unavoidable
on the opened-up instrument, these must only be carried out
by qualified 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
+/0°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.

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
correctiy with the front chassis.
Operation of the module
Provided that ail hints given in the operating instructions of
the HM8001 Mainframe were followed especially for the
selection 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 HM8001 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 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.
