TESTER IMPEDANCE METER SL-030

Features:

This compact pocket test meter can not only measure the surface impedance 

but also measure the resistance to ground 

The measurement range is from 103 ohms to 1012 ohms with an accuracy 

of +1/2 range

The SL-030 adopts ASTM standard D-257 parallel electrode sensing method,

which can easily and repeatedly measure various conductive type, electrostatic 

discharge type, and insulating type surface

Instructions:

1)To measure the surface impedance, place the tester on the surface to be 

measured, and press and hold the red TEST button; continuously lit LED 

indicate the magnitude of the measured surface impedance 

103=1 kohm (Green LED)

104-10k Ohm (Green LED) 

105-100k Ohm (Green LED) 

106-1M Ohm (Yellow LED) 

107-10 MQ (Yellow LED) 

108-100 megohm (Yellow LED) 

109-1000 MQ (Yellow LED) 

1010-10000 Mohm (Yellow LED) 

1011=100000 Mohm (Yellow LED) 

1012-1000000Mohm (Red LED) 

1012 Insulated (Red LED)

2)Measure resistance to ground:

Insert the ground wire into the ground, place the tester on the surface to be 

measured and hold down 

the TEST button; the continuous light LED indicates the magnitude of the 

resistance to ground; the unit of this measurement is ohms
