RESISTIVITY INDICATOR
61-100-0401
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.
Calibration : The tester should be calibrated every year. A test resistance can be
applied across the parallel bars to verify if the tester is within
specification, using a resistance decade box.
