TRISAN S8 Appliance categories and test sequences
3 LEADS Class I and Class II Insulation resistance test required to be isolated from protective earth
Suitable appliance category for testing any earthed leads or power boards.
This test is conducted with the standard 500VDC. electrical strength test. Applied to obtain an insulation resistance
figure which is required to be above 1 M ohm. for a PASS result.
Select LEADS
Press START
Measures: Electrical continuity (A –N) …………….. less than 100k ohm………………………………..for PASS
Polarity A-N swap
Short circuit between A-N
Earth resistance (socket earth to chassis earth with earth probe connect)…….less than 1 ohm…….PASS
Insulation resistance (A - N short to EARTH)………..greater than 1M ohm……………………PASS
If power boards are to be tested, all outlet sockets are to be tested individually.
2 wire or figure 8 leads
For 2 wire leads a prompt warning will be displayed detecting no earth.
Two conductor lead?
START (Y) RESET (N)
Press START second prompt:
Fit conductive cloak
and connect to front
panel socket before
proceeding
Press START to run test
Measures: Electrical continuity (A –N) …………….. less than 100k ohm………………………………..for PASS
Polarity A-N swap (Not important)
Short circuit between A-N
Insulation resistance (A - N short to Earth Test Probe or Cloak)…greater than 1M ohm…… …PASS
Cloak is vital for test integrity. This provides the return path for dangerous leakage currents. Wrap entire lead with
conductive cloak and connect to earth probe.
