The 2525 is a 500 VA (5 kV, 100 mAAC) rated Hipot Tester. It features the latest technology and is designed for electrical safety testing applications that require a high current Hipot test. With its advanced features, product reliability and cost-effective price, the 2525 is ideal for quick and easy production line testing.

• 500 VA Hipot Tester
• 10 Memories, 3 Steps per memory
• Built-in Continuity Test
• Meets 200 mA Short Circuit Requirements
• Fully Adjustable Ramp & Dwell

1. 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.
2. 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.
3. LCD Display: The Liquid Crystal Display is the main readout for the operator and programmer of the test settings and test results.
4. Continuity Check 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 continuity test. Please refer to page 34 for details on connecting the adapter box between the 2525 and the device under test.
5. Power Switch: Rocker-style switch with international ON ( | ) and OFF (0) markings.
6. Set Key: Use this key to advance forward through the setup menus.
7. 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.
8. 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.
9. Exit Key: Use this key when you desire to enter the Run Mode to initiate a test.
10. 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.
11. High Voltage Arrow (LED Indicator): This indicator flashes to warn the operator that high voltage is present at the high voltage output terminal.
12. Return Output Jack: For the connection of the detachable 5 foot (1.52 m) black return test lead. This lead is always used when performing a test.

1. Remote Interface Signal Output: 9 pin D subminiature female connector which provides; Pass, Fail and Test in process signals.
2. Remote Interface Signal Input: 9 pin D subminiature male connector which provides remote control access over Test, Reset and Interlock.
3. Calibration Enable Key: To enter the calibration mode press this key while the instrument is being powered ON.
4. Thermal Fan: To cool the instrument.
5. 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.
6. Chassis Ground (Earth) Terminal This safety terminal should be connected to a good earth ground before operation.
7. Input Power Receptacle: Standard IEC 320 connector for connection to a standard NEMA style line power (mains) cord.

The above diagram shows how to connect the adapter box to the model 2525 and to the device under test.

The adapter box allows you an easy way to connect an item that is terminated in a two or three-prong line cord. If you are testing a product which is terminated in a three-prong plug, you are also required to perform a continuity or ground bond test on the ground conductor of the DUT to the chassis or dead metal of the product. With the 2525, you can perform both the hipot and continuity tests at the same time by activating the continuity function on the instrument.

When the 2525 tests the ground conductor of the line cord, if the resistance of the ground conductor exceeds 1Ω, the hipot will signal a continuity failure. If continuity is present, high voltage is applied to both conductors of the line cord to insure that all current carrying conductors in the primary circuit are tested. When testing products with two prong plugs, do not activate the continuity circuit.
