1 Safety Information
This instrument is Safety Class III according to IEC classification and has been designed to
meet the requirements of EN61010-1 (Safety Requirements for Electrical Equipment for
Measurement, Control and Laboratory Use).
This instrument has been tested in accordance with EN61010-1 and has been supplied in a
safe condition. This instruction manual contains some information and warnings which have to
be followed by the user to ensure safe operation and to retain the instrument in a safe
condition.
This instrument has been designed for indoor use in a Pollution Degree 2 environment in the
temperature range 5°C to 40°C, 20% - 80% RH (non-condensing). It may occasionally be
subjected to temperatures between +5° and -10°C without degradation of its safety. Do not
operate while condensation is present.
This instrument is fitted with a rechargeable Lithium ion polymer battery; do not expose the
instrument to heat sources or high-temperature environments such as an unattended vehicle in
the sun. Only recharge the battery, in the instrument, using the charger supplied.
Do not incinerate the instrument and/or battery; refer to the Service Guide for information on
battery replacement and disposal.
Use of this instrument in a manner not specified by these instructions may impair the safety
protection provided.
WARNING!
All accessible parts will be at the same voltage as the outer body of the SMA input socket. In
particular, note that the shells of both USB connectors are galvanically connected to the body of
the SMA input and will therefore be at earth ground potential when either USB port is connected
to a desktop PC. To maintain user safety under all other circumstances it is essential that the
input is not connected to a voltage above 30Vdc or 30Vrms with respect to earth ground which
is the limit of Safe Extra Low Voltage (SELV) by IEC definition.
The instrument shall be disconnected from all voltage sources before it is opened for any
adjustment, replacement, maintenance or repair. Any adjustment, maintenance and repair of
the opened instrument shall be carried out only by a skilled person in conjunction with the
Service Guide, see Maintenance section.
Do not wet the instrument when cleaning it; see Maintenance section for further details.
The following symbols are used on the instrument and in this manual.
Direct Current
CAUTION – refer to accompanying documentation.
Damage to the instrument may occur if these precautions are ignored.
Adaptor/Charger
The adaptor/charger supplied has a universal input voltage rating of 100-240VAC, 50/60Hz. It is
a Class II (double insulated) device, fully approved to EN 60950-1 and UL 60950-1 (UL listing
E245390).
