INSTRUMENTSETUP
The OMNIA comes pre-loaded with one default test file. The file is an AC withstand
test loaded with default parameters.
(Figure 1. Main Menu Screen)
1. Choose the correct input line voltage on the rear panel of the instrument, either
115V AC or 230V AC.
2. Connect the line cord into the rear of the instrument and plug the male end of the cord
into a grounded power source.
3. Plug the interlock connector into the Signal Input connector on the rear panel of
the instrument. OMNIA is equipped with a Remote Interlock feature, which utilizes a set
of closed contacts to enable the instrument’s output. In order to perform a test, the
interlock connector must be plugged into the Signal Input connection of the rear panel
of the instrument.
4. Turn the POWER switch to ON.
The initialization screen will appear. After three seconds the Main Menu screen will
appear as shown below. (See Figure 1.)
WARNING: LOCATE A SUITABLE TESTING AREA WITH A THREE-
PRONG, GROUNDED OUTLET. BE SURE THAT YOUR THREE-PRONG OUTLET HAS
BEEN TESTED FOR PROPER WIRING. ALSO, MAKE SURE YOU READ THE SAFETY
CHECKLIST OF THIS GUIDE BEFORE STARTING TO TEST.

TEST CONNECTIONS (8104):
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.
Under the output ports on the back panel, plug the black high voltage lead in the
high voltage terminal. This acts as a line and neutral together.
Plug the Kelvin lead into the Sense (+) jack and the high current test lead into the
current jack. These two red leads act as the ground connection.
Connect the ground return clip to dead metal on the chassis of the DUT. Plug the
Kelvin lead into the Sense (–) jack and the return lead into the return jack. Always
check to make sure a good connection is made between the DUT and the return clip.
Plug the line cord of the DUT into the adapter box receptacle.
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.

TEST CONNECTIONS (8105 & 8106):
Under 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.
Connect the ground return clip to dead metal on the chassis of the DUT.
Plug the line cord to the DUT into the adapter box receptacle.
Only the rear output connections may be used for connecting the adapter box on
the 8105 and 8106 models. (See Figure 5)

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 to a DUT. (See Figure 6)
Plug the black return lead into the Return terminal and the black Kelvin lead into
the Sense (–) lead. Then connect the high voltage lead terminated in a red clip into
the (H.V.) terminal on the front panel of the instrument.
Attach the clip-terminated end of the return lead to the dead metal on the chassis
of the DUT. If necessary, a 10 x 20 cm piece of foil can be attached to the
enclosure to simulate a full hand contact to the DUT. This foil acts as the return
point. The Return and Sense (–) jack are attached to the foil. Always check to make
sure a good connection is made between the DUT and the return clip.
Attach the high voltage lead to the current-carrying conductors of the DUT.
If performing a ground test on a Class I product (connection not shown), connect
the red high current lead into the Current terminal and the red Kelvin lead into
the Sense (+) jack. The clip at the other end will connect to the ground pin of
the DUT plug.
INITIATING A TEST
To perform a test, you should save steps, return to the main menu and hit the
correlating soft key for "Perform Tests." You can now initiate a test through the
front panel by pressing the green TEST button. The red RESET button will abort
a test in process.
