Test Procedures
Pass/Fail Indication
The ST-1D checks receptacles for proper wiring, and give a pass/fail indica-
tion of voltage drop and line voltage. These tests are performed immediately
upon insertion of the SureTest into the receptacle.
Wiring Verification
The ST-1D checks receptacle wiring for the following conditions:
Correct wiring, no ground, polarity reversed, no hot, or no neutral or hot and
ground reversed. These conditions are indicated on the wiring indicators.
Insert the ST-1D into the receptacle for indication of the wiring condition.
WARNING
An indication of “No Ground” on the wiring indicators indicates a
safety hazard is present. Defective grounds must be repaired prior to
the GFCI test.
The ST-1D will not indicate a reversal of the ground and neutral
connections, detect two hot connections, or indicate simultaneous
defects.
