NAME

 

FUNCTION

 

RESET

 Button / Red Indicator  

When  lit,  indicates  that  the  HT-3000  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.    

 

TEST

 Button / Yellow 

Indicator 

When lit, indicates that the HT-3000 is ready to test the connected equipment. The yellow 

TEST

 indicator goes 

out when the 

TEST

 Button is pressed.   

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 circuit has more than three ohms resistance, 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 
continuity test is defeated by the operator, both LED's will be lit for the duration of the test. 

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.   

Full Voltage

 LED 

If full voltage is successfully reached, the 

Full Voltage

 LED will light and the high voltage duration timer starts. 

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.   

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. 

Voltage Meter 

Provides visual indication to the operator of the actual output voltage of the Tester.  Used to set the automatic 
voltage level during the setup procedure.   

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. 

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.
