Maintenance and cleaning 

 

6.1 

Battery replacement 

 

Warning:

 To prevent faulty measurements and resulting injuries, replace the battery as soon as 

the battery symbol appears. Make sure that the test leads are neither connected to the circuit to be 
checked, nor to the device before you open the case. 
 
To replace the battery, remove the screws (11) from the battery compartment cover (10) and remove the 
cover from the battery compartment. Replace the batteries by batteries of the same type and mount the 
cover back on. 

6.2 

System reset 

In case of a severe system error, a system reset can solve the problem. To do so, push the Reset button 
with a thin object during switch-on. Note that this causes furher settings to be reset to factory defaults. 
 

7 

Disposal 

 

Due to the contained pollutants, batteries must not be disposed of as household waste. They must be 
given to collection points designed fort hat purpose. 
 
In order to comply with the ElektroG (German Electrical Equipment Act), we take our devices back. We 
either re-use them or give them to a recycling company which disposes of the devices in line with law. 
 
If you have any questions, please contact PCE Instruments. 
 
WEEE reg.-no. DE69278128 
 

 

All products are CE and RoHs approved.
