ITEM
NAME
FUNCTION
1
RESET Button / Red Indicator
When lit, indicates that the HT-S tester is unarmed. This button must be pushed before the
TEST
button is functional.
When the
RESET
button is pressed, the red
RESET
indicator goes out and the yellow
TEST
indicator is lit. PRESSING
THE
RESET
BUTTON AT ANY TIME STOPS THE TEST.
2
TEST Button / Yellow Indicator
When lit, indicates that the HT-S tester is ready to test the connected equipment. The yellow
TEST
indicator goes out when
the
TEST
button is pressed.
3
Voltage Meter
Provides visual indication to the operator of the actual output voltage of the HT-S tester. Used to set the test voltage level
during the setup procedure.
4
Ramp Bar Graph LED’s
Individual LED’s light in sequence from left to right as the test voltage ramps from zero to full voltage. LED’s turn off
(ramp back down) at end of test.
5
Hipot Pass LED
At the end of the preset high voltage duration time, if no failures are encountered, the green light will light and the test will
terminate.
6
Full Voltage LED
If full voltage is successfully reached, the
Full Voltage
LED will light and the high voltage duration timer starts.
7
Ground OK / Ground Open LED's
Indicates result of Ground Continuity test between grounding pin of the line cord and exposed metal parts of the equipment
under test. If the ground path resistance it is higher than the indicated on the ground setting, or if the leads are not properly
connected, the red
Ground Open
LED will light, the internal buzzer will sound, and the test will be terminated. If the
ground circuit resistance is acceptable, the green continuity LED will light and the test will continue. If the Ground Check
switch is defeated by the operator, both LED's will be lit for the duration of the test.
8
Excess Leakage LED
Indicates failure of leakage current test. If leakage current between the primary circuit and ground is higher than the preset
value, the red LED will light, the internal buzzer will sound, and the test will be terminated.
9
Hipot Fail LED
Indicates failure of high voltage test. If arcing or a flashover of the insulation system between primary parts and ground is
encountered, the red breakdown LED will light, the internal buzzer will sound, and the test will be terminated.
10
Return Lead Receptacle
Grounded banana plug receptacle. The 18 AWG Test Return Lead provided is connected here.
11
High Voltage Device Receptacle
NEMA 5-15R orange receptacle. For connection of the equipment under test. See items 11a and 11b for slots description.
11a
High Voltage Output
On the NEMA plug, the two top vertical slots are tie together, the high voltage to perform the Dielectric Withstand test
comes true these two slots.
11b
Ground Continuity Measurement
Point
On the NEMA plug, the bottom round slot is the ground continuity measured point. Ground continuity test circuit is
measured from this slot (Item 11b) to the Return Lead Receptacle (Item 10).
12
High Voltage Test Jack
Red High Voltage jack. For connection of high voltage test lead for testing insulating materials, etc. This High Voltage
Jack is standard on models HT4200S and HT-3000S, and optional on models HT-2800S and HT-2000S
13
AC/DC Switch
Selects AC or DC output. Changing switch setting does not change output until the next time the Reset button is pushed.
This option is only available on
HT-3000S & HT-4200S
model.
