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
(measurement device, power cable, product cd, optional acces-
sories). 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.

1.4 Transport and storage
Please keep the original packaging 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!
Dry indoor storage is required. After exposure to extreme
temperatures, wait 2 hours before turning the instrument on.
1.5 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!
– The available supply voltage must comply with the value
specified on the type plate.
– 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
1.6 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
operated n the presence of excessive dust, humidity, chemical
vapors nor 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 hours prior to operation.
For safety reasons, the instrument must only be operated from
an outlet with a safety earth or via an isolation transformer of
class II. In principle the instrument may be used in any position,
