1.1

Symbols

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

Unpacking

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

Positioning

Two positions are possible: According to Fig. 1 the front feet
are folded down and are used to lift the instrument so its front
points slightly upward (appr. 10 degrees).
If the feet are not used (Fig. 2) the instrument can be stacked
safely with many other HAMEG instruments.
In case several instruments are stacked (Fig. 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 and Storage

Please keep the shipping 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!
Dry indoors storage is required. After exposure to extreme
temperatures 2h for accomodation to ambient temperature
before turning the instrument on.
1.5

Safety instructions

The instrument conforms to VDE 0411/1 safety standards ap-
plicable 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 interna-
tional 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.
Do not disconnect the safety ground either inside
or outside of the instrument!
In case of doubt the power connector should be checked ac-
cording to DIN VDE 0100/610:
– The line voltage of the instrument as shown on the type label
must correspond to the line voltage used.
– Only qualified personnel may open the instrument
– 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

Proper 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. Opera-
ting temperature is +5...+40°C. Storage or transport limits are
–20...+70°C. In case of condensation 2 hours for accomodation
to ambient temperature before turning the instrument on.
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, sufficient ventilation must be assured as
convection cooling is used. For continuous operation prefer a
horizontal or slightly upward position using the feet.
