6-2 Insulation Resistance Measurement ④ Read the resistance value from the LCD. DANGER ● Always test the circuit or equipment to ensure it is surely de-energized before measurement according to the instruction of 6-1. ● To avoid electrical shock, measurements must be performed on de- energized circuits only. -
Page 10: Continuity Measurement (Resistance Tests)
●Terminal connection of insulation resistance test ● Principle of Continuity Measurement (Resistance Test) In case of testing insulation of insulated wire and cable against the earth Resistance value can be obtained by applying a certain current to the at direct current, connecting - pole of power to cable conductor, + to the resistance under test and measuring the voltage generated on the both earth obtains smaller measuring value, compared with connecting the sides of the resistor under test. -
