If the cable is o.k. there is aproblem between the wrist strap and the skin of the arm. 

Cause for it may be a very dra skin or to long hairs. 

A humidity lotion may solve this problem 

If you have always this problem exchange the wrist strap ! 

 

Limits 

 

The lower and upper limits are fixed by lower and upper calibrated resistor moduls.  

Factory default is: 

wrist strap test 

lower limit 

750kΩ 

 

 

 

 

 

 

upper limit 

35 MΩ  

 

Other limits are possible without extra charge. The limits can be changed by the customer 
anytime  

  see adjustment of the limits.

Exchange Batteries 

 

 
The appliance possesses battery supervision. If the battery 
voltage is below the limit, the red “low Battery” LED shines. 
In this case the batteries must be change.  
The battery compartment is on the underside of the appliance. 
When installing in new batteries look for the polarity !!  

 

Important !  Use alkaline batteries only !
