i Series / iX Series 225
LOAD is wired to the user's load (unit under test, UUT). Refer to the figures in this section for
examples of proper connections.
Refer to the power source manual to determine the appropriate wire gauge needed for the output
wiring.
9.6.5.3 External Sense Wiring
The external sense wires of the power source must be connected at the output of the power
source and NOT at the output of the OMNI or at the load. If the external sense wires were
connected at the load or the OMNI output, the power source error amplifier would lower the
effective OMNI impedance making the system unsuitable for IEC 555-3 or IEC 1000-3-3 flicker
testing.
Refer to the figures in this section for examples of proper external sense connections.
