SAFETY NOTES

 

 

Reference. Please use utmost attention. 

 

Do not exceed the maximum allowable input range of any function 

 

Insulated personnel body protective equipment up to 690V. 

 

WARNINGS 

 

In order to avoid electrical shock, the valid safety and VDE regulations regarding 
excessive contact voltages must receive utmost attention, when working with 
voltages exceeding 120V (60V) DC or 50V (25V) rms AC. The values in brackets are 
valid forlimited ranges (as for example medicine and agriculture). 

 

Prior to measurement ensure that the test leads and the test instrument are in 
perfect condition 

 

When using this instrument only the handles of the probes may be touched – do not 
touch the probe tips. 

 

This instrument may only be used within the ranges specified and within low voltage 
systems up to 690V. 

 

Prior to usage ensure perfect instrument function (e.g. on known voltage source).
