Warranty; Maintenance; Protective Switch Off; Power Supply - Hameg Instruments Hm5012-2 Handbuch

If condensed water exists in the instrument it should be
acclimatized before switching on. In some cases (e.g.
extremely cold instrument) two hours should be allowed
before the instrument is put into operation. The instrument
should be kept in a clean and dry room and must not be
operated in explosive, corrosive, dusty, or moist
environments. The instrument can be operated in any position,
but the convection cooling must not be impaired. The
ventilation holes may not be covered. For continuous operation
the instrument should be used in the horizontal position,
preferably tilted upwards, resting on the tilt handle.
The specifications stating tolerances are only valid if the
instrument has warmed up for 20 minutes at an ambient
temperature between +15°C (+59°F) and +30°C (+86°F).
Values without tolerances are typical for an average instrument.

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 2 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 must
contact and notify the distributor who has sold the product.
Each instrument is subjected to a quality test with 10 hour
burn in before leaving the production. Practically all early
failures are detected by this method. In the case of shipments
by post, rail or carrier the original packing must be used.
Transport damages and damage due to gross negligence are
not covered by the guarantee.
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 guarantee claims.

Maintenance

The exterior of the instrument should be cleaned regularly
with a dusting brush. Dirt that is difficult to remove on the
casing and handle, the plastic and aluminium parts, can be
removed with a moistened cloth (99% water +1% mild
detergent). Spirit or washing benzine (petroleum ether) can
be used to remove greasy dirt. The screen may be cleaned
with water or washing benzine (but not with spirit (alcohol) or
solvents), it must then be wiped with a dry clean lint free
cloth. Under no circumstances must the cleaning fluid get
into the instrument. The use of other cleaning agents can
attack the plastic and paint surfaces.
Subject to change without notice

Protective Switch Off

This instrument is equipped with a switch mode power supply.
It has both over voltage and overload protection, which will
cause the switch mode supply to limit power consumption to
a minimum. In this case a ticking noise may be heard.

Power supply

The instrument operates on mains/line voltages between
100V AC and 240V AC . No means of switching to different input
voltages has therefore been provided.
The power input fuse is externally accessible. The fuse holder
and the 3 pole power connector is an integrated unit. The
power input fuse can be exchanged after the rubber connector
is removed. The fuse holder can be released by lever action
with the aid of a screwdriver. The starting point is a slot located
on contact pin side. The fuse can then be pushed out of the
mounting and replaced.
The fuse holder must be pushed in against the spring pressure
and locked. Use of patched fuses or short circuiting of the
fuse holder is not permissible; HAMEG assumes no liability
whatsoever for any damage caused as a result, and all warranty
claims become null and void.
Fuse type:
Size 5x20mm; 0.8A, 250V AC fuse;
must meet IEC specification 127,
Sheet III (or DIN 41 662
or DIN 41 571, sheet 3).
Time characteristic: time lag.
Attention!
There is a fuse located inside the instrument within the
switch mode power supply:
Size 5x20mm; 0.8A, 250V AC fuse;
must meet IEC specification 127,
Sheet III (or DIN 41 662
or DIN 41 571, sheet 3).
Time characteristic: fast (F).
The operator must not replace this fuse!
