2900 SERIES QUICK START GUIDE
This Demonstration/Quick Start Guide is designed to provide you with assistance in starting to use your 2900 series instrument. Make sure before you begin using the instrument that you are familiar with the proper safety precautions. Information concerning safety precautions and complete operating instructions can be found in the manual.
To begin, click on one of the sections below:
Front Panel Controls
- LCD DISPLAY: The Liquid Crystal Display is the main readout for the operator and programmer of the test settings and test results.
- RESET SWITCH: This is a momentary contact switch. If an out-of-range reading is detected during a hipot test or an IR test or if continuity failure occurs, the red failure lamp within the switch will light. To reset the system for the next test, press and release this switch. This switch may also be used to abort a test in progress.
- TEST SWITCH:This is a momentary contact switch. Press the green switch to turn on the high voltage output when in test mode. The indicator lamp within the switch will light when continuity is “good”, if continuity mode is enabled.
- POWER SWITCH: Rocker-style switch with international ON ( | ) and OFF (0) markings.
- SET KEY: Use this key to advance forward through the setup menus.
- DOWN ARROW (∨): Use this key to decrement numeric values in the setup mode. This key also used to toggle ON/OFF functions. Also may be used to decrease output voltage during a test in 10-volt increments.
- UP ARROW (∧): Use this key to increment numeric values in the setup mode. This key also used to toggle ON/OFF functions. Also may be used to increase output voltage during a test in 10-volt increments.
- EXIT KEY: Use this key when you desire to enter the Run Mode to initiate a test.
- HIGH VOLTAGE OUTPUT JACK: For the connection of the detachable 5-foot (1.52 m) red high voltage test lead. The silicone rubber insulation is flexible for easy handling and is rated at 30KVDC. The jack is recessed for safety when this lead is not being used.
- HIGH VOLTAGE ARROW (LED INDICATOR): This indicator flashes to warn the operator that high voltage is present at the high voltage output terminal.
- RETURN OUTPUT JACK: For the connection of the detachable 5 foot (1.52 m) black return test lead or three-prong receptacle adapter box. This jack is always used when performing a test. Please refer section E. Adapter Box connection for details on connecting the adapter box between the instrument and the device under test.
- CONTINUITY CHECK OUTPUT JACK: For the connection of the detachable 5 foot (1.52 m) black return test lead. This jack is always used when performing a continuity test. Please refer section E. Adapter Box connection for details on connecting the adapter box between the instrument and the device under test.
Rear Panel Controls
- THERMAL FAN: To cool the instrument.
- INPUT POWER SWITCH: Line voltage selection is set by the position of the switch. In the down position, it is set for 115-volt operation, in the up position it is set for 230-volt operation.
- REMOTE INPUT/OUTPUT: 9-pin D subminiature male connector for remote control of test and reset function as well as for monitoring PASS, FAIL, and PROCESSING output relay signals.
- CHASSIS GROUND (EARTH) TERMINAL: This safety terminal should be connected to a good earth ground before operation.
- INPUT POWER RECEPTACLE: Standard IEC 320 connector for connection to a standard NEMA style line power (mains) cord.
- FUSE RECEPTACLE: To change the fuse unplug the power (mains) cord and turn the fuse cap counter clockwise to remove the fuse.
- CALIBRATION ENABLE KEY: To enter the calibration mode press this key while the instrument is being powered ON
The 2900 series comes ready with the following factory default settings in memories 1 - 5. These default settings will remain unless overridden with your own test program. Before beginning, please make sure the input voltage selector switch is set correctly on the back panel (115 or 230).
- Input Voltage: 115 or 230 volts AC country specific
- Lock: OFF
- Test: W - I (2975)
Dielectric Withstand Test Mode
- Voltage Output: 1,240 volts AC
- High Current Trip: HI-LMT: 10 mA
- Low Current Trip: LO-LMT: 0 mA (2955, 2965, 2975)
- Ramp Timer: 0 second (2955, 2965, 2975)
- Dwell Timer: 1 second
- Voltage Type: AC
- AC Output Frequency: 60 Hz
- Continuity: OFF
Insulation Resistance Mode (model 2975)
- Voltage Output: 1,000 volts DC
- High Resistance Trip: I - High: 0 MΩ
- Low Resistance Trip: I - Low: 1 MΩ
- Delay Timer: 2 seconds
These abbreviated parameters stand for the following:
- SET: This is the parameter settings review screen.
- W - SET: This is the parameter settings review screen for Dielectric Withstand test mode.
- I - SET: This is the parameter settings review screen for Insulation Resistance test.
- M1: Indicates the memory location of the current settings.
- M1_: Indicates that an Insulation Resistance test and a Dielectric withstand test has been linked together. (2975)
- 1.0 S: The dwell timer is set to a test duration of 1 second.
- 1.24 kVAC: The test voltage is set to 1,240 volts AC.
- 10.00 mA: The high leakage current trip point is set to 10 milliamps.
To change factory defaults simply press the "set" key on the front panel. This will toggle through the following parameters:
- W-Mode (shown on model 2975) or Mode (shown on model 2955 & 2965)
- W-Volt (shown on model 2975) or Volt (shown on model 2955 & 2965)
- W-High (shown on model 2975) or High (shown on model 2955 & 2965)
- W-Low (shown on model 2975) or Low (shown on model 2955 & 2965)
- W-Ramp (shown on model 2975) or Ramp (shown on model 2955 & 2965)
- W-Dwell (shown on model 2975) or Dwell (shown on model 2955 & 2965)
- W-Freq (shown on model 2975) or Freq (shown on model 2955) (Available in AC Hipot Mode Only)
- W-Continuity (shown on model 2975) or Continuity (shown on model 2955 & 2965)
- I – Volt (2975 Only)
- I – High (2975 Only)

- I – Delay (2975 Only)
The "up" and "down" arrow keys will toggle and change the settings on each parameter. Pressing exit will automatically save those parameters.
To connect the 2900 series to a DUT, first connect the black return lead into the front panel receptacle. Then connect the high voltage lead (w/ red clip) or probe, which-ever one you are using for your application into the high voltage receptacle on the front panel.
Next attach the black return clip to exposed or dead metal located on the chassis of the DUT. Always connect the ground return first.
If you are using the high voltage clip, make sure you attached the red clip to the current carrying conductors of the DUTs circuitry. If you are using the test probe, simply apply the probe to the appropriate current carrying conductors.
The adapter box is provided as an optional accessory for the 2900 series of Hipot Testers. This provides an easy way to connect to a DUT that is terminated in a two-prong or three-prong line cord.
In order to use the adapter box, continuity must be enabled. This is set up in the instruments menus. First plug the return lead from the adapter box into the front panel return jack on the 2900 series Hipot tester. Then plug the high voltage lead from the adapter box in the front panel high voltage jack. If you are testing a three-prong DUT, then connect the continuity cable into the back panel continuity jack on the instrument and attach the clip terminated end to the chassis of the DUT. If it is a two-prong DUT then this cord must be removed. Finally plug the DUT into the adapter box.
