1.2 Setting Up the Instrument
As shown in the illustrations, small hinges on the bottom
stands can be folded out to set up the instrument in a
slightly inclined position. Please make sure that the stands
are completely folded out to ensure a stable position.
The instrument must be positioned in a manner that allows
the user to disconnect the unit from the mains at any time
and without restrictions.
1.3 Safety
The instrument fulfils the DIN EN 61010-1 (VDE 0411 part 1
regulations for electrical measuring, control and laboratory
instruments and was manufactured and tested accordin-
gly. It left the factory in perfect safe condition. Hence it
also corresponds to European Standard EN 61010-1 and
International Standard IEC 1010-1. In order to maintain this
condition and to ensure safe operation the user is requi-
red to observe the warnings and other directions for use
in this manual. Housing, chassis as well as all measuring
terminals are connected to safety ground of the mains. The
instrument is designed in compliance with the regulations
of protection class II.
Fig. 1.1: Operating positions
The exposed metal parts are checked against the mains
poles with 2200 V DC voltage. The instrument is in ac-
cordance with overvoltage category CAT II (600 V).
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. Sepa-
rating the grounds is prohibited. Never use the product if
the power cable is damaged. Check regularly if the power
cables are in perfect condition. Choose suitable protective
measures and installation types to ensure 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:
❙
in case of visible damage,
❙
in case loose parts were noticed,
❙
if it does not function any more,
❙
after prolonged storage under unfavourable conditions
(e.g. like in the open or in moist atmosphere),
❙
After rough handling during transport (e.g. packaging
that does not meet the minimum requirements by post
office, railway or forwarding agency).
Prior to switching on the product, it must be ensured that
the nominal voltage setting on the product matches the no-
minal voltage of the AC supply network. If it is necessary to
set a different voltage, the power fuse of the product may
have to be changed accordingly.
1.4 Intended Operation
The measuring instrument is intended only for use by per-
sonnel familiar with the potential risks of measuring electri-
cal quantities. For safety reasons, the instrument 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 manufac
-
turer, without the product‘s ventilation being obstructed.
If the manufacturer‘s specifications are not observed, this
can result in electric shock, fire and/or serious personal in
-
jury, and in some cases, death. Applicable local or national
safety regulations and rules for the prevention of accidents
must be observed in all work performed.
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
Use the measurement instrument only with original ROHDE &
SCHWARZ measuring equipment, measuring cables and power
cord. Never use inadequately measured power cords. Before each
measurement, measuring cables must be inspected for damage
and replaced if necessary. Damaged or worn components can da-
mage the instrument or cause injury..
