Safety Precautions
Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid.
Even original spare parts may be installed only by authorized ser-
vice personnel.
In case the equipment was opened by unauthorized personnel,
no warranty regarding personal safety, measurement accuracy,
conformity with applicable safety measures or any consequential
damage is granted by the manufacturer.
Repair and Parts Replacement by authorized service personnel
When the instrument is opened, voltage conducting parts may be
exposed. The instrument must be disconnected from the measur-
ing circuit before performing repairs or replacing parts. If repair of
a live open instrument is required, it may only be carried out by
trained personnel who are familiar with the dangers involved.
Defects and Extraordinary Strains
If it may be assumed that the instrument can no longer be oper-
ated safely, it must be removed from service and secured against
unintentional use.
Safe operation can no longer be relied upon:
• If the device demonstrates visible damage
• If the instrument no longer functions, or if malfunctioning
occurs
• After long periods of storage under unfavorable conditions (e.g.
humidity, dust or extreme temperature (see “Ambient Condi-
tions” on page 64)
1.1 Use for Intended Purpose
• The multimeter is a portable device which can be held in the
hand during the performance of measurements.
• Only those types of measurements described in section 5 may
be performed with the measuring instrument.
• The measuring instrument, including measurement cables and
plug-on test probes, may only be utilized up to the maximum
specified measuring category (see page 63 and the table on
page 8 regarding significance).
If the measuring categories specified for the measuring instru-
ment and the measurement cables differ from each other, the
lower category applies to the application.
• Overload limits may not be exceeded. See technical data on
page 58 for overload values and overload limits.
• Measurements may only be performed under the specified
ambient conditions. See page 64 regarding operating temper-
ature range and relative humidity.
• The measuring instrument may only be used in accordance
with the specified degree of protection (IP code) (see page 64).
