2205 QUICK START GUIDE
This Demonstration/Quick Start Guide is designed to provide you with assistance in starting to use your 2205 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
- POWER SWITCH: Rocker-style switch with international ON ( | ) and OFF (0) markings.
- TEST SWITCH: This is a momentary contact switch. Press the green switch to energize the high voltage output. When the dwell function is "0," high voltage will remain ON until a reject occurs or the RESET button is pushed. If the dwell function is anything other than "0", the high voltage will be present only for the programmed time.
- RESET SWITCH: This is a momentary contact switch. If a failure is detected during a test, 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.
- DISPLAY: The Display is the main readout for the test settings and test results. Scalar values are indicated via a digital display.
- SET KEY: Use this key to enter Setup Mode and advance forward through the setup menus.
- DOWN ARROW (∨): Use this key to decrement numeric values in the setup mode.
- UP ARROW (∧): Use this key to increment numeric values in the setup mode.
- EXIT KEY: Use this key when you desire to exit Setup Mode enter the Run Mode to initiate a test. This key will also toggle the digital display between Resistance, Voltage and Dwell during and after tests.
- HIGH VOLTAGE OUTPUT JACK: For the connection of the detachable 6 foot (1.82 m) red high voltage test lead. The jack is recessed for safety when this lead is not being used.
- RETURN JACK: For the connection of the detachable 6 foot (1.82 m) black, shielded return test lead.
- RESISTANCE LED INDICATOR: This indicator illuminates when resistance is displayed in either test or setup mode.
- VOLTAGE LED INDICATOR: This indicator illuminates when voltage is displayed in either test or setup mode.
- DELAY LED INDICATOR: This indicator illuminates when delay time is displayed in either test or setup mode.
- DWELL LED INDICATOR: This indicator illuminates when dwell time is displayed in either test or setup mode.
- HIGH VOLTAGE LED INDICATOR: This indicator flashes to warn the operator that high voltage is present at the high voltage output terminal.
- DISCHARGE LED INDICATOR: Indicates charge status of device under test. Green < 30V, Red > 30V
- MEGOHM RANGE LED INDICATOR: This indicator illuminates when the displayed resistance measurement or limit is in megohms.
- GIGOHM RANGE LED INDICATOR: This indicator illuminates when the displayed resistance measurement or limit is in gigohms.
Rear Panel Controls
- VENTILATION: 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.
- PLC REMOTE I/O: 9 pin D subminiature male connector for remote I/O.
- 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.
The 2205 comes ready with the following factory default settings on the instrument. 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
- Resistance Lo-Limit: 0.1 megohms
- Voltage Output: 500 V
- Delay: 1 (1 second)
- Dwell: 1 (1 second)
To change factory defaults simply press the "set" key on the front panel. This will toggle through the following parameters:
- Resistance Lo-Limit
Use the up and down arrows to adjust the parameters. Once you press the Exit button, the parameters will automatically be saved.
To connect the 2205 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.
