NAME

 

FUNCTION

 

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.    

 

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. 

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. 

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 test 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.  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.
