NAME
FUNCTION
1
Appliance Inlet / Fuse holder /
Power Switch
Use supplied cord set to connect tester to appropriate source of supply. Replace line fuse. Turn Tester ON/OFF.
Power switch must be accessible during operation
2
Fuse replacement warning / Rating
of supply
Specifies replacement fuse and required supply voltage.
3
Testlink OUTPUT Receptacle
The Output Testlink Cableset lead is connected here. The cableset is included when you get Testlink option.
4
Testlink RETURN Receptacle
The Return Testlink Cableset lead is connected here. The cableset is included when you get Testlink option.
5
Testlink
Allows connection with GF-30AC-T for Ground Bond Test. A cableset is included when you get this option.
6
Interlock
This is a safety feature, when in short-circuited the HT works regular, when open stops immediately its function.
7
Relay Interface
Relay Interface/PLC Interface. Test signals through relay contacts/coils (Optional).
8
Ground Check Switch
Enables or disables the Ground Continuity test.
Turn ON for use with three-wire (grounded) power supply cords.
Turn OFF for use with two-wire power supply cords.
(When ON, conducts Ground Continuity test between the chassis and the grounding pin of the line cord of the
equipment being tested. When OFF, Ground Continuity test is bypassed for testing of double-insulated equipment
and other types of equipment without a grounding pin in the line cord.)
9
Ground Resistance Setting
Adjustment
Used to adjust the Ground Continuity pass/fail point setting. See “Ground Continuity” on the Adjustment section for
more information
10
Ground Offset Button
This button can perform two different functions. Pressing and holding it for 1 second, the HT-S will measure and
display on the front display the Ground Continuity resistance of the EUT under test. Pressing and holding the button
for 5 seconds will compensate the resistance of the test cables of fixture, see “Ground Continuity Offset Adjustment”
and “Ground Continuity Resistance Measurement” sections for more details.
11
Leakage Limit Adjustment
Used to adjust the trip level for the excessive leakage current test. See "Leakage Current Level" on Adjustment
section for more information.
12
Test Time Adjustment
Used to adjust high voltage test duration. See "Adjustment of the High Voltage Test Duration" section for this
procedure.
13
Ramp Time Adjustment
Used to adjust the amount of time used to increase the high voltage from zero volts to the required level. See "High
Voltage Ramp Time" on Adjustment section for correct procedure.
14
Directions
Provides directions for tester operation to test personnel.
15
Voltage Adjust
Used to adjust the High Voltage output. See "High Voltage Level" on the Adjustment section for correct procedure.
16
Calibration resistor
This resistor (optional) may be used to verify the leakage current.
