TIMT Line Insulation Monitor Tester
5
FEATURES
• Testing of IT Supply Systems derived from high impedance transformers.
• Test between earth reference and phase with output connections for a multimeter.
• Test Insulation monitoring alarm by adjusting the potentiometer to verify the audio and visual indication.
INSTRUCTION MANUAL
A) Multimeter voltage test:
Socket Outlet Voltage Test 1: Test between “Earth Reference“ and Line 1 (Blue) Reading ± 115 Volts.
Socket Outlet Voltage Test 2: Test between “Earth Reference“ and Line 2 (Red) Reading ± 115 Volts.
B) Remove “Multimeter” and set switch to blue or red phase, turn the potentiometer clockwise until the line
insulation monitor indicates both audio and visual.
C) Verify operation of Line Insulation Monitor testing all socket-outlets
.
These values can be captured on a ‘‘COC’’ test report.
Note: The Voltage values could fluctuate due to changes in load.
