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.
Check setting of line voltage selector whether it corresponds
to the actual line voltage.
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 the instrument can be combined with
many other Hameg instruments.
In case several instruments are stacked 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 in-
struments. 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. Improper packaging may void the
warranty!
Storage
Dry indoors storage is required. After exposure to extreme
temperatures 2 h should be allowed before the instrument is
turned on.
Safety instructions
The instrument conforms to VDE 0411/1 safety standards appli-
cable to measuring instruments and 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 accor-
ding to DIN VDE 0100/610.
Disconnecting the protective earth internally or ex-
ternally is absolutely prohibited!
As soon as the voltages applied to the INPUT termi-
nals exceed levels accepted as safe to the touch
all applicable safety rules are to be observed!
DC voltages must be disconnected from earth.
AC voltages shall be derived from a safety isolation
transformer and must also be disconnected from
earth.
Before the safety connectors on the INPUT termi-
nals are pulled off it must be assured that the
voltage has been switched off, otherwise there may
be danger of accident, even danger of life!
If instruments of protective class I are connected
to the OUPUT terminals
must be connected separately to the test object. If
this is not observed there is danger of life!
This instrument may only be opened by qualifi ed
personnel. Before opening all voltages have to be
removed!
The safety connectors may become quite hot at
high current levels!
STOP STOP
– The line voltage selector must be properly set for the line
voltage used.
– Opening of the instrument is allowed only to qualifi ed per-
sonnel
– Prior to opening the instrument must be disconnected from
the line 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:
