Don’t measure over 10 seconds when
measurement resistance is lower than 2MΩ with use of 500V
measurement resistance is lower than 5MΩ with use of 1000V
measurement resistance is lower than 10MΩ with use of 2500V
measurement resistance is lower than 20MΩ with use of 5000V
When press IR to select insulation resistance measurement but no test
voltage output, press arrow buttons to 500V/1000V/2500V/5000V voltage
range.
1) When performing insulation resistance tester, remove all power from the
circuit to be measured or disconnect all the power.
2) insert the red test line into the "LINE" input port, black test line to "GUARD",
green to "EARTH"
3) Connect the red and black crocodile clip to the tested circuit, negative
voltage outputs from LINE terminal.
4) select one of the following insulation resistance measurement mode:
Continuous measurement
1) Press TIME button to select continuous measurement mode, there is no
timer icon on the LCD screen
2) Press left arrow button and hold right arrow TEST button for 1 second to
carry out and output insulation resistance test voltage, the red Test button
light up,
blinks on every 0.5 seconds.
3) Press TEST button turn off the voltage output after test, TEST button lights
off,
disappears. The CLD shows the current insulation resistance test
