Unpacking

While unpacking, check the package contents for com-
pleteness (measuring instrument, power cable, product
CD, possibly optional accessories). After unpacking, check
the instrument for mechanical damage occurred during
transport and for loose parts inside. In case of transport
damage, please inform the supplier immediately. The in-
strument must not be operated in this case.

Setting Up the Instrument

Two positions are possible: .
Fig. 1
Fig. 2
Fig. 3
According to Fig. 1 the front feet are folded down and are
used to lift the instrument so its front points slightly up-
ward (approx. 10 degrees). If the feet are not used (Fig. 2)
the instrument can be stacked safely with many other HA-
MEG instruments. In case several instruments are stak-
ked (Fig. 3) the feet rest in the recesses of the instrument
below so the instruments can not be inadvertently mo-
ved. Please do not stack more than 3 instruments. A hig-
her stack will become unstable, also heat dissipation may
be impaired.

Safety

This instrument was built in compliance with VDE 0411
part 1, safety regulations for electrical measuring instru-
ments, control units and Iaboratory equipment. It has
been tested and shipped from the plant in safe condition.
It is in compliance with the regulations of the European
standard EN 61010-1 and the international standard IEC
61010-1. To maintain this condition and to ensure safe op-
eration, the user must observe all instructions and warn-
ings given in this operating manual. Casing, chassis and
all measuring ports are connected to a protective earth
conductor. The instrument is designed in compliance with
the regulations of protection class 0.
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
For safety reasons, the instrument may only be operated
with authorized safety sockets. The power cord must be
plugged in before signal circuits may be connected. Never
use the product if the power cable is damaged. Check reg-
ularly if the power cables are in perfect condition. Choose
suitable protective measures and installation types to en-
sure that the power cord cannot be damaged and that no
harm is caused by tripping hazards or from electric shock,
for instance.
If it is assumed that a safe operation is no longer possible,
the instrument must be shut down and secured against
any unintended operation.
Safe operation can no longer be assumed:
❙ If the measuring instrument shows visible damage
❙ If the measuring instrument no longer functions properly
❙ After an extended period of storage under unfavorable
conditions (e.g. outdoors or in damp rooms)
❙ After rough handling during transport (e.g. packaging that
does not meet the minimum requirements by post office,
railway or forwarding agency).
In case of doubt the power connector should be checked
according to DIN VDE 0100/610:
❙ Only qualified personnel may open the instrument
❙ Prior to opening the instrument must be disconnected
from the line and all other inputs/outputs.

Intended Operation

The measuring instrument is intended only for use by per-
sonnel familiar with the potential risks of measuring elec-
trical quantities. For safety reasons, the measuring instru-
ment may only be connected to properly installed safety
socket outlets. Separating the grounds is prohibited. The
power plug must be inserted before signal circuits may be
connected. The product may be operated only under the
operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being ob-
structed. If the manufacturer's specifications are not ob-
served, this can result in electric shock, fire and/or serious
personal injury, and in some cases, death. Applicable local
