A
TEST
(Figure 6, Test Lead Connection)
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.
