Practical surface resistivity meter.
In accordance with ASTM D-257th
Product specifications:
Dimensions: 130x70x25mm
Weight: 170 g
Power: 1 x 9V PP3 battery (supplied with the tester)
Display: 3 green led, 6 yellow led, 2 red led
Voltage & measurement process: Method of parallel bars (ASTM D-257)
Packaging: Supplied in a PVC pouch with ground leakage
Tester measurements:
Surface resistivity checking:
Place the device onto the surface to be tested, press and hold the test
button. The led that illuminates constantly is the decade measured.
Checking resistance to ground:
Insert the ground lead into the ground/earth leakage socket. This isolates the
test probe on the right side of the meter. Connect the alligator clip to your
ground connection.
Place the device onto the surface to be tested, press and hold the test
button. The led that illuminates constantly is the decade measured.
The measurement is now a resistance to ground in Ω instead of Ω/square.
