Correct operation

HAMEG modules are destined to be operated
normally in the mainframe HM8001-2. If they are
used in other systems it must be ensured that
they are operated with the correct supply voltages
(see specification). All applicable safety rules are
to be observed.
The instruments are destined for operation in
clean and dry rooms. Operation is precluded in
dusty or moist atmosphere , if there is danger of
explosion, and if aggressive chemicals are
present.
The operating temperature range is 0 ... + 40 de-
grees C, the strorage and transport temperature
range –20 ... +70 degrees C. In case of suspected
condensation a 2 h acclimatizing period has
to be awaited before the instrument may be
operated.
Safety regulations require that the mainframe be
only operated from mains outlets with a safety
ground connector or via an isolation transformer
of safety class 2. No special orientation of the
instrument is prescribed, however, sufficient air
circulation must be ensured. Continuous opera-
tion will require a horizontal or slightly tilted
(front feet extended) position.
The ventilation holes must not be
obstructed!
Please note: Because of electromag-
netic reasons, it is not permitted to use
STOP
two moduls of type HM8040-3 in the
same mainframe.
