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
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. 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 according
to DIN VDE 0100/610.
Disconnecting the protective earth internally or
externally is absolutely prohibited!
– 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:
– Visible
damages
– Damage to the power cord
– Damage to the fuse holder
– Loose
parts
– No operation
– After longterm storage in an inappropriate environment ,
e.g. open air or high humidity.
– Excessive transport stress
Operating conditions
The instruments are destined for use in dry clean rooms. Ope-
ration in an environment with high dust content, high humidity,
danger of explosion or chemical vapors is prohibited.
Operating temperature is 0 .. +40 degrees C. Storage or trans-
port limits are –20 .. +55 degrees C. In case of condensation two
hours are to be allowed for drying prior to operation.
For safety reasons operation is only allowed from 3 terminal
connectors with a safety ground connection or via isolation
transformers of class 2. The instrument may be used in any
position, however, suffi cient ventilation must be assured as
convection cooling is used. For continuous operation prefer a
horizontal or slightly upward position using the feet.
