Safety Precautions
Defects and Extraordinary Strains
If it may be assumed that the instrument can no longer be
operated 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 Con-
ditions” on page 60)
1.1 Use for Intended Purpose
• The respective multimeter is a portable device which can be
held in the hand during the performance of measurements.
• Only those types of measurements described in chapter 5 may
be performed with the measuring instrument.
• The measuring instrument, including measurement cables and
plug-on test probes, may only be utilized within the specified
measuring category (see page 59 and the table on page 8
regarding significance).
• Overload limits may not be exceeded. See technical data on
page 54 for overload values and overload limits.
• Measurements may only be performed under the specified
ambient conditions. See page 60 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 60).
