Test progress
The PAT400 displays all tests to be performed within the selected test group.
Each test is run sequentially and the results displayed for each test before proceeding to the next test.
A “FAIL” on any test will prevent further testing for safety purposes.
Test screen example:
Class I asset
Interruption to automatic testing
Testing proceeds automatically unless an action is required from the operator.
Follow “on-screen” instructions as they appear.
3.4
Remote probe and clip
Some tests will require the use of the remote probe and clip. These are used where the asset under test has no earth return (Class II
assets). Test using the remote probe include:
Insulation testing on Class II equipment
Continuity/bond testing on Class I equipment
Touch leakage testing
Differential leakage test on Class II
Substitute leakage on Class II
The PAT400 will instruct the operator when the remote probe needs to be connected.
Example of remote probe application
Class II insulation test (Riso)
Live and neutral are shorted together automatically in the PAT (RED LINK) and a voltage (250 V or 500 V) is applied between the shorted
L/N and the remote probe.
The probe is connected to any metallic locations on the “appliance under test” to ensure there is no breakdown of the insulation.
