Grounding Resistance Tester
GOAL: check that all the touch accessible parts are properly connected to the protective earth connection.
PRINCIPLE: Apply a current in between each metallic accessible part and the earth protection connection, then measure the voltage in between those two parts and check with the Ohmic law that the calculated resistance is lower than the value required by the standard. The DUT is not connected to mains!
Excellent performation
Electrical safety wall, protect the operator, DUT and the testerCan set the resistance offset value4-terminal test method, eliminate the contact resistanceStandard PLC interfaceResistance upper-limit, lower-limit alarmOpen-circuit alarm function
TEST CONDITIONS (according to the main standards):
♦ Current 10, 25 A AC or DC, or 2 x In
♦ Voltage from 6 to 12 volts AC or DC
♦ Resistance < 0, 1ohm, 0, 2 ohm or 0, 5 ohm
♦ Time > 5 s, 1mn or not defined
