1.1

Symbols

Symbol 1: Attention, please consult manual
Symbol 2: Danger! High voltage!
Symbol 3: Ground connection
Symbol 4: Important note
Symbol 5: Stop! Possible instrument damage!
1.2

Unpacking

Please check for completeness of parts while unpacking. Also
check for any mechanical damage or loose parts. In case of
transport damage inform the supplier immediately and do not
operate the instrument.
1.3

Positioning

Two positions are possible: According to picture 1 the front
feet are used to lift the instrument so its front points slightly
upward. (Appr. 10 degrees)
If the feet are not used (picture 2) the instrument can be com-
bined with many other HAMEG instruments.
In case several instruments are stacked (picture 3) the feet rest
in the recesses of the instrument below so the instruments can
not be inadvertently moved. Please do not stack more than 3
instruments. A higher stack will become unstable, also heat
dissipation may be impaired.

Transport

Please keep the carton in case the instrument may require later
shipment for repair. Losses and damages during transport as
a result of improper packaging are excluded from warranty!
1.5

Storage

Dry indoor storage is required. After exposure to extreme tem-
peratures, wait 2 hr before turning the instrument on.
1.6

Safety instructions

The instrument conforms to VDE 0411/1 safety standards appli-
cable to measuring instruments and it left the factory in proper
condition according to this standard. Hence it conforms also
to the European standard EN 61010-1 resp. to the internatio-
nal standard IEC 61010-1. Please observe all warnings in this
manual in order to preserve safety and guarantee operation
without any danger to the operator. According to safety class 1
requirements all parts of the housing and the chassis are con-
nected to the safety ground terminal of the power connector.
For safety reasons the instrument must only be operated from
3 terminal power connectors or via isolation transformers. In
case of doubt the power connector should be checked according
to DIN VDE 0100/610.
Do not disconnect the safety ground either inside
or outside of the instrument!
– Opening of the instrument is only allowed to qualified per-
sonnel
– Prior to opening, the instrument must be disconnected from
the line voltage and all other inputs/outputs.
In any of the following cases the instrument must be taken out
of service and locked away from unauthorized use:
– Visible damage
– Damage to the power cord
– Damage to the fuse holder
– Loose parts
– No operation
– After long term storage in an inappropriate environment,
e.g. open air or high humidity.
– Excessive transport stress

Proper operating conditions

Operation in the following environments: industry, business and
living quarters, small industry. The instruments are intended
for operation in dry, clean environments. They must not be ope-
rated in the presence of excessive dust, humidity, nor chemical
vapours in case of danger of explosion.
The maximum permissible ambient temperature during ope-
ration is +5 °C to +40 °C. In storage or during transport the
temperature limits are: –20 °C to +70 °C. In case of exposure to
low temperature or if condensation is suspected, the instrument
must be left to stabilize for at least 2 hrs prior to operation.
In principle the instrument may be used in any position, however
sufficient ventilation must be ensured. Operation for extended
periods of time requires the horizontal or tilted (handle) position.
Nominal specifications are valid after 30 minutes warm-up at
23 °C. Specifications without tolerances are typical values taken
of average production units.
