Intended Operation

The measuring instrument is intended only for use by
personnel familiar with the potential risks of measuring
electrical quantities. For safety reasons, the measuring
instrument may only be connected to properly installed
safety socket outlets. Separating the grounds is prohibited.
The power plug must be inserted before signal circuits
may be connected.
Use the measuring instrument only with original HAMEG mea-
suring equipment, measuring cables and power cord. Never use
inadequately measured power cords. Before each measurement,
measuring cables must be inspected for damage and replaced
if necessary. Damaged or worn components can damage the
instrument or cause injury.
The product may be operated only under the operating
conditions and in the positions specified by the manufac-
turer, without the product's ventilation being obstructed.
If the manufacturer's specifications are not observed, this
can result in electric shock, fire and/or serious personal in-
jury, and in some cases, death. Applicable local or national
safety regulations and rules for the prevention of accidents
must be observed in all work performed.
The measuring instrument is designed for use in the fol-
lowing sectors: Industry, residential, business and com-
mercial areas and small businesses.
The measuring instrument is designed for indoor use only.
Before each measurement, you need to verify at a known
source if the measuring instrument functions properly.
To disconnect from the mains, the low-heat device socket on the
back panel has to be unplugged.

Ambient Conditions

Permissible operating temperatures during the operations
range from +5 °C to +40 °C. During storage or transporta-
tion the temperature may be between –20 °C and +70 °C.
In case of condensation during transportation or storage
, the instrument will require approximately two hours to
dry and reach the appropriate temperature. It can then be
operated. The measuring instrument is designed for use in
a clean and dry indoor environment. Do not operate with
high dust and humidity levels, if danger of explosion exists
or with aggressive chemical agents. Any operating posi-
tion may be used; however adequate air circulation must
be maintained. For continuous operation, a horizontal or
inclined position (integrated stand) is preferable.
The maximum operating altitude for the instrument is 2000
m. Nominal data with tolerance details apply once the am-
bient temperature of 23 °C has been reached after about
30 minutes. Values without tolerance details are reference
values of an average instrument.

Cooling

The heat produced inside the power supply is guided to
the exterior via temperature-controlled fan. This fan,
combined with a cooling element, is located in a "cooling
duct" which is positioned across the instrument. The air is
drawn at the left side and exhausted at the right side of the
instrument. This helps minimize the dust exposure to the
instrument as much as possible. However, it is necessary
to ensure that there is sufficient space on both instrument
sides for the heat exchange.
Do not obstruct the ventilation
holes!
If the temperature inside the instrument still increases to
more than 80°C, a channel-specific overheat protection in-
tervenes. Affected outputs will automatically be switched
off.

Warranty and Repair

HAMEG instruments are subject to strict quality controls.
Prior to leaving the manufacturing site, each instrument
undergoes a 10-hour burn-in test. Nearly every premature
failure will be detected in intermittent operation. This is
followed by extensive functional quality testing to examine
all operating modes and to guarantee compliance with
the specified technical data. The testing is performed with
testing equipment that is calibrated to national standards.
The statutory warranty provisions shall be governed by
the laws of the country in which the HAMEG product was
purchased. In case of any complaints, please contact your
supplier.
Applicable only in EU countries:
If your instrument still requires repair work, customers
within the EU can process repairs directly with HAMEG to
accelerate the procedures. The HAMEG customer service
(see RMA) is available for repair services even once the
warranty period ends.
Return Material Authorization (RMA):
In any event, before returning an instrument, request a
RMA number either via internet (http://www.hameg.com)
or by fax. If you require technical support or suitable pack-
aging (original box), please contact the HAMEG Service:
