4. EXPLANATION OF SYMBOLS 

DC voltage

AC voltage

DC voltage negative potential (DC)

Phase display from 100 to 690V - 50/60Hz

when used as a "single-pole" phase tester. Continuity test symbol

Rotating field display clockwise

Rotating field display anticlockwise

Device for work to be performed with voltage present

Battery replacement symbol

DC

AC

The voltage tester shows the following symbols:

5. INSERTING/CHANGING THE BATTERIES

The voltage tester is operated with two micro-batteries
(type AAA, in the scope of delivery).
Proceed as follows to insert or change the batteries:
• Loosen the screw on the battery compartment lid                            

(10) with a suitable screw driver and remove it.

• Insert two batteries (AAA) into the battery compartment.                      

Observe the polarity information in the battery                   
compartment. If possible, use alkaline batteries. They guarantee a 
longer service life. Then, carefully close and screw down the battery 
compartment lid again. The batteries need to be changed if the       
"Low Bat      " symbol lights up on the LCD display or when the LCD 
display stays dark after contacting both test tips.

  The voltage tester will show no reading if the batteries are flat. The 

device must not be operated with flat batteries or without batteries.    
To prevent damage to the device from leaking batteries, remove the 
batteries from the device if you will not be using it for a longer period. 
For the same reason, we recommend that you remove flat batteries 
immediately.

 

6. MEASURING POINT LIGHTING

The voltage tester has a battery-operated measuring point lamp. Press 
button (9) to switch this lamp on. The lamp stays on as long as this 
button is kept pressed. When the button is released, the lamp goes off. 
The lighting button is arranged in such a way that it can also be pressed 
during low impedance measurements.
