ITEM
NAME
FUNCTION
1
RESET Button / Red Indicator
When lit, indicates that the HT-3000PR 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 TEST.
2
TEST Button / Yellow Indicator
When lit, indicates that the HT-3000PR is ready to test the connected equipment. The yellow
TEST
indicator goes out
when the
TEST
Button is pressed.
3
Ground OK / Ground Open LED's
Indicates result of Ground 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 swtich is
defeated by the operator, both LED's will be lit for the duration of the test.
4
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.
5
Full Voltage LED
If full voltage is successfully reached, the
Full Voltage
LED will light and the high voltage duration timer starts.
6
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.
7
Hipot Pass LED
At the end of the preset high voltage duration time, if no insulation breakdowns are encountered, the green light will light
and the test will terminate.
8
Voltage Meter
Provides visual indication to the operator of the actual output voltage of the Tester. Used to set the test voltage level during
the setup procedure.
9
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.
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 receptacle. For connection of the equipment under test.
12
High Voltage Test Jack
Red High Voltage jack. For connection of high voltage test lead for testing insulating materials, etc. This option is only
available on
HT-3000PR
model.
13
AC/DC Switch
Only for
HT-3000PR
model Selects AC or DC output. Changing switch setting does not change output until the next time
the Reset button is pushed.
