DRK 156 Surface Resistance Tester

Product details

This vest-pocket surface resistance tester can test the surface impedance and also can test the resistance to ground .Its measuring range is from 103(Ω) to 1012(Ω).Its accuracy is ±1/2.

It is used to test all kinds of conduction, static electricity draining and insulation surface. 

Product application
1 Test surface impedance：
Put the tester on the specimen’s surface，then press the red button（TEST）continuously the LED which continuous lighting shows the data. The data unit is ohm..

103=1 kilohm　　　　green LED
104=10 kilohm　　　　 green LED
105=100 kilohm　　 　 green LED
106=1 megohm　　　 　yellow LED
107=10 megohm 　　 　yellow LED

108=100 megohm 　　　yellow LED
109=1000 megohm　　　yellow LED

1010=10000 megohm　　 yellow LED
1011=100000 megohm　　yellow LED
1012=1000000 megohm　 red LED
·1012= insulating  red LED

2 Test the resistance to ground
Insert the grounded-wire into grounded electrical outlet（Ground）so that to insulate the tester’s electrode on the right（the same side with the electrical outlet）.Connect the clamp into the grounded wire.
Put the tester on the specimen’s surface，then press the red button（TEST）continuously，the LED which continuous lighting shows the data. The data unit is ohm.
