Page 6: An Introduction To Dielectric Withstand Testing With The Ht-3000P
Because of sparking during a dielectric test failure, it is not safe to conduct dielectric withstand tests in combustible atmospheres. It is imperative that a good ground be provided to the HT-3000P. Before connecting the HT-3000P, ensure that a low-resistance ground is provided by the building wiring. If the HT- 3000P is used on a high-resistance grounding circuit, dangerous high voltages may be present to the operator. -

Safety Techniques The high voltage circuit of the HT-3000P can be shut off at any time by pressing the RESET button. The HT-3000P has been provided with a Reset switch to provide an unarmed "Standby" setting when it is energized, but idle. When the red RESET button is lit the tester will not provide high voltage until the RESET button and the TEST button have been pressed in order. -
Page 8: Defeating The Ground Check
HT-3000P may show a "PASS". To allow the HT-3000P to test equipment using a two wire power supply cord, the Ground Check can be defeated by turning the rear panel Ground Check switch to the Off position. -
Page 9: Sporadic Leakage Current Failures
If the leakage current adjustment of the HT-3000P is set to 20 mA AC and almost all examples of the model being tested are still failing, the primary circuit capacitance of the equipment may be too high to allow the AC dielectric withstand test to be used. -

Testing Equipment with non-Standard Plugs or Pigtail Operation The front panel of the HT-3000P is provided with a NEMA Type 5-15R receptacle, suitable for testing cord-equipped single-phase products designed for use on a 15 amp branch circuit in North America. -
Page 11: Introduction And Specifications
Operator instructions are printed on the rear panel for quick reference. The HT-3000P allows custom setups for voltage ramp, test time and leakage limit. The Ground check can be defeated by a switch on the rear panel for testing of products using a two wire power supply cord. - Page 12 Leakage Test Provided; 5 mA AC/5 mA DC factory set pass/fail point, user adjustable. Operation Instructions Provided on rear panel. Table 1. HT-3000P Specifications *Ground Continuity Pass/Fail Level can be adjusted from .5 to 5 ohms during the calibration procedure.

Page 19: Initial Checkout Procedure
The following procedure will verify that the HT-3000P is working correctly. We recommend that this procedure be conducted periodically to ensure proper operation of the tester. (A Compliance West HTT-1 function tester may also be used to verify the HT-3000P is working correctly.) The following items are needed to conduct this procedure: - A three inch piece of 18 AWG insulated hookup wire with each end stripped back ½". -
Page 20: Setting Up The Ht-3000P For Production Line Testing
This section describes procedures for setting the Pass/Fail leakage current level, high voltage ramp time, high voltage level, and high voltage test time. The HT-3000P is calibrated as shown below at the factory to be usable without adjustment in the majority of applications. If the factory settings are acceptable, you may skip this section. -

Most safety agencies will allow a shorter test (usually 1 sec. vs. 1 min.) if the voltage is increased by 20%. The HT-3000P is factory set for 1200 volts AC, a voltage level used for the one second test for many types of equipment. Consult the safety agencies for the required voltage level for the type of equipment being tested. -

(usually 1 second vs. 1 minute) if the voltage is increased by 20%. The HT-3000P is factory set for 2 seconds. Consult the safety agencies for the test time for the type of equipment being tested. If a different test time is required, use this procedure to set it. -
Page 23: Operating Techniques
The operation of the HT-3000P should be audited daily by conducting the tests described in the Initial Checkout Procedure section of this Manual. Compliance West also offers the model HTT-1, which can be used to quickly verify the operation of your HT-3000P. Contact the factory for details. -

This will ensure that the test voltage has been bled off. The operator can now remove the equipment from the HT-3000P and connect another. The HT-3000P should then be armed by pressing the RESET button. When ready, the operator then presses the TEST button and the test procedure will be conducted again. -

3-ohm 1/4 w 1% resistor. Service Information The HT-3000P is warranted to the original purchaser for a period of 1 year. This warranty does not cover problems due to misuse or neglect. Malfunctions which occur within the limits of the warranty will be corrected at no charge. -
Page 28: Calibration Access
Calibration Access Use the following procedures to gain access to the calibration adjustments of your instrument. 1. Set Line Power switch to OFF. 2. Disconnect the power cord from the rear of the instrument. 3. Remove the two upper screws on each side of the unit. 4. -
Page 29: Voltage Calibration Adjustment
LED has been attained. Voltage Calibration Adjustment Use the following procedure to calibrate the output voltage. Ensure that all test leads are removed from the HT-3000P. Turn OFF the HT-3000P tester. To enter the Calibration Mode you MUST follow the following sequence: - Hold in both the Test and Reset buttons. - Page 30 "V2" again. The voltage is now be calibrated. 14. Turn Off the HT-3000P tester. 15. The voltage can be verified by turning on the HT-3000P, running a test, and using the 1000:1 voltage probe to check the meter at different voltages. If the voltages are not within +/- 2% at each voltage, the voltage calibration must be performed again starting at step 1 above.
