PE-335 carries out the earth resistance
measurements by using the three-electrodes method. 2 mA
measuring current permits earth resistance tests without
tripping earth leakage current breakers in the circuit under
test. PE-335 Digital Earth Resistance Meter comes with
functions as data-holding, timer for test function, etc. |
Electrical multifunction network analyzer for
LOOP, PSC & Earth Test PE-425 incorporates a built-in
Earth Tester and Loop/PSC tester for ranges from 0,3 to 2000
Ohms. It is possible to display the PSC Line, Neutral and Earth.
There is also included a built-in voltmeter in the PE-425. |
