TECHNICAL GUIDE

3.   Swing the OSCILLATING WEIGHT as the illustration 

for more than three seconds so that the movement 
detects the electricity generation and it turns to the 
normal hand movement mode. 

Note: 

When swinging the OSCILLATING WEIGHT, take 

care so as not to touch the probes of the tester.

4.   Wait  for  more  than  10  seconds  until  a  stable  measurement  is  obtained,  and  then  read  the 

measurement.

5.   Make sure the read value is less than 

0.80 μA
