Safety Warnings

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 61 and the table on page 8 
regarding significance).

• Overload limits may not be exceeded. See technical data on 

page 56 for overload values and overload limits.

• Measurements may only be performed under the specified 

ambient conditions. See page 59 regarding operating 
temperature range and relative humidity.

• The measuring instrument may only be used in accordance 

with the specified degree of protection (IP code) (see page 61).

1.2

Meanings of Danger Symbols

Warning concerning a point of danger 
(attention: observe documentation!)
