Correct Operation; Warranty And Repair; Maintenance; Overtemperature Protection - Rohde & Schwarz Hameg Instruments HM8040-3 Manual

Exceeding 42 V
By series connecting all outputs the 42 V
limit can be exceeded which means that
touching live parts may incur danger of
life! It is assumed that only qualifi ed and
extensively instructed personnel are al-
lowed to operate this instrument and/or
the loads connected to it.

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 specifi cation). 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, suffi cient 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
STOP
use two moduls of type HM8040-3 in
the same mainframe.

Warranty and Repair

HAMEG instruments are subjected to a strict qua-
lity control. Prior to leaving the factory, each ins-
trument is burnt-in for 10 hours. By intermittent
I m p o r t a n t h i n t s
operation during this period almost all defects are
detected. Following the burn-in, each instrument
is tested for function and quality, the specifi cations
are checked in all operating modes; the test gear
is calibrated to national standards.
The warranty standards applicable are those of
the country in which the instrument was sold.
Reclamations should be directed to the dealer.
Only valid in EU countries
In order to speed reclamations customers in EU
countries may also contact HAMEG directly. Also,
after the warranty expired, the HAMEG service will
be at your disposal for any repairs.

Under no circumstances any fl uid must
enter the instrument. Other than the
STOP STOP
specifi ed cleaning materials may affect
plastic or lacquered surfaces.

Overtemperature protection

If an internal temperature of 75 ... 80 degrees C
is exceeded the outputs and the displays will be
turned off. This will be indicated by 3 blinking
dashes in the left and right displays. As soon as
the displays return to the normal display of the
values set the instrument will again be ready to
operate. The outputs will remain disabled until the
pushbutton OUTPUT
