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. |

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. |
