4. Measuring and testing

4.1. General information

The 

upper display line

 

shows currently selected 

measurement range. 

When this indication is 

flashing you have to con-

nect special accessories 

e.g. TMZ or MZ

The 

lower display line

 

shows the actual  

metered value. 

The instrument is switched off automatically  

approximately 60 seconds after the last  

measurement in order to extend battery life. In the 

display the indication „off“ appears (exception: see 

section 4.6 frequency measurements). The backlight 

turns off when no measurement result is applied or 

when the battery is low. 

With the ON/OFF button engaging the  

METRALINE EXM25 to voltage, call the 

display test and switch-off the device.

With the function button you can select 

the designated measurement range:
