Test time, current and resistance can be displayed simultaneously
Out put current:5~30A. Ground resistance range:0~600mohm.
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!
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
