Measurement Method:

• When testing, especially for high resistance materials, make sure that the test wires do not touch or overlap
• for accurate testing,operator couldn't touch the electrode by hand during operation
• the meter should be grounded with equipped ground cord during operation
• the surface resistance of insulative plate should be larger than 1.0x 10e12 ohm when insulative plate need to be used during testing.
• It is recommend to calibrate electrode each month,place the two electrodes on the metal plate and the measured resistance shoulder lower than 1000 ohm

A. Measure surface resistivity - parallel electrode
It can be used to measure the resistance of surface uniform materials and multilayer materials quickly

• Make the meter to be placed on the object surface,2 parallel bar need to touch object surface
• Dial the switch to 10v voltage and press the test button keeping 5-10 seconds until the testing result is stable,If the resistance is lower than 1.0 x 10 e6 ohm,please record the result.If the resistance is equal or larger than 1.0 x 10e6 ohm,please switch to 100V and test again
• Switching the test voltage to 100 volts may result in a resistance reading less than 1.0x10e6 ohm.When this occurs,use the reading of the 100 volt test voltage.
• When test surface resistance,humidity and temperature will be displayed on the LCD screen
• the testing value will be shown after releasing the test button 15 sec.
• Surface resistance is ohm

B. Measure surface resistance(point to point)-2 five lbs weight

• Plug each terminal of the 2 connecting cord into the 3.5mm jacks and the other end connected to 2 five lbs weights.
• Make the 2 five lbs to be shown on the measured material surface,the distance between the 2 five lbs weights is 1 meter or the farthest distance that two weights can be separated on the surface of an object
• Dial the switch to needed voltage 10V or 100V
• Press the test button until testing result is stable
• the test shall include areas of the surface that are easily worn or visibly soiled
• Surface resistance is ohm

C. Measure surface resistance(concentric ring probe)optional

• Plug each terminal of the connecting cord into the 3.5mm jacks and the other end connected to concentric ring probe.
• Dial the switch to needed voltage 10V or 100V
• Make the probe to be shown on the measured material surface,press the test button keeping 5-10 seconds until the testing result is stable
• the test shall include areas of the surface that are easily worn or visibly soiled
• Surface resistance is ohm

D. Measure volume resistance- 2 five lbs weights

• Plug the 2 connecting cord into the 2 five lbs weights and the other end connected to meter.
• Make one weight on the measured object surface
• Make the other weight on the metal plate,like below picture
• Dial the switch to needed voltage 10V or 100V
• Press the test button to record the resistance after the meter is stable or 15 sec later.
• the test shall include areas of the surface that are easily worn or visibly soiled
• Volume resistance is ohm.

E. Measure Point to Grounding Point resistance-2 five lbs weight

• Plug one cord terminal into the five lbs weight and the other end to meter
• Make the 5 lb weight into the testing surface center
• Connect the other cord terminal to meter and the other terminal to grounding reference point
• Dial the switch to needed voltage 10V or 100V
• Press the test button to record the resistance after the meter is stable or 15 sec later
• the test shall include areas of the surface that are easily worn or visibly soiled
• Point to grounding point resistance is ohm.
