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 intended 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

This instrument has been designed and tested
in accordance with IEC Publication 1010-1,
Safety requirements for electrical equipment
for measurement, control, and laboratory use.
It corresponds as well to the CENELEC
regulations EN 61010-1. 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 instrument 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),

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

HAMEG warrants to its customers that the
products it manufactures and sells will be free
from defects in materials and workmanship for a
period of two years. This warranty shall not apply
to any defect, failure or damage caused by
improper use or inadequate maintenance and
care. HAMEG shall not be obliged to provide
service under this warranty to repair damage
resulting from attempts by personnel other than
HAMEG representatives to install, repair, service,
or modify these products.
In order to obtain service under this warranty,
customers have to contact and notify their
distributor.
Each instrument is subjected to a quality test with
ten-hour burn-in before leaving the factory.
Practically all early failures are detected by this
method. In the case of shipments by post, rail,
or carrier it is recommended to preserve the
original packing carefully. Transport damages and
damage due to gross negligence is not covered
by warranty.
In the case of a complaint, a label should be
attached to the housing of the instrument that
describes briefly the faults observed. If at the
same time the name and telephone number
(dialing code and telephone or direct number or
department designation) is stated for possible
queries, this helps towards speeding up the
processing of warranty claims.
Maintenance
Various important properties of the module
should be checked carefully in certain intervals
to ensure that all signals and measurement
results are displayed with the accuracy on which
the technical data are based.
When removing the case detach mains/line cord
and any other connected cables from case of the
mainframe HM8001. 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.
