frOntPANelcOntrOlS sense (+) teRMInAL: Connector used to attach the (+) sense lead for 4-wire kelvin current measurement. this connection provides for accurate current measurement during the Ground Bond test. CuRRent outPut teRMInAL: Connector used to attach the high current output lead, adapter box high current lead or test fixture high current lead to the instrument.
bacKPANelcOntrOlS (Model 8204/8254, Back Panel) CALIBRAtIon Button: to put the instrument into the calibration mode push this button and turn on the power switch simultaneously. sCAnneR ConneCtoR: For connection of optional external scanner. ReMote sIGnAL outPut: 9-Pin D sub-miniature female connector for monitoring PAss, FAil, and PROCessiNG output relay signals.

changIngthetyPeOFteSt Once the test has been added, the parameters for the chosen test type will appear. Use the soft keys to edit parameters on the right side of the screen (examples: Frequency, Arc Detect and Ramp- hi). Use the arrow keys (up, down, left, right) to scroll between test parameters on the left side of the screen (examples: voltage, hi-limit t, lo-limit t, dwell time, ramp time, etc.).

changIngthetyPeOFteSt Use the soft keys to edit parameters on the right side of the screen. Use the arrow keys (up, down, right, left) to scroll between test parameters on the left side of the screen. Use the numeric keypad to change a parameter value. Once the desired value has been entered, press eXit to go back to the setup tests screen.
PerfOrMIngAteSt teSt cOnnectIOnS (8204/8254) the adapter box is an easy way to connect a Device Under test (DUt) that terminates in either a two or three-prong line cord. the following diagram shows how to connect the adapter box to the instrument and the DUt (see Figure 4). if you are testing a Class i product, you may elect to perform a Ground Bond test on the ground circuit of the DUt along with the hipot test.

PerfOrMIngAteSt teSt cOnnectIOnS (8206/8256 & 8207/8257) Using the DUt output ports on the back panel, plug the line lead from the adapter box into the l terminal and the neutral lead into the N terminal. Next attach the red ground lead from the adapter box to the GND terminal. Attach the black case return lead into the case terminal.
Page 11
PerfOrMIngAteSt teSt cOnnectIOnS there is no ground circuit on the DUt of a Class ii product. therefore, test leads may be utilized to connect the OMNiA ii to a DUt. (see Figure 6) Plug the black return lead into the Return terminal and black kelvin lead into the sense (-) lead.
