9.6.6 Operation
9.6.6.1 General
The OMNI impedance network adds resistive and inductive impedance to the output of selected
California Instruments power sources/systems to provide power source impedance levels
specified for IEC 555-3 flicker testing. For normal (low impedance) power source operation, the
impedance that OMNI adds may be shunted by bypass relays selected on the OMNI front panel.
9.6.6.2 Omni i Front Panel Controls/Indicators
Power Switch and Lamp
A power switch turns the OMNI control circuits on or off. A lamp above the switch illuminates
when power is on.
Flicker On/Off Switch and Lamps
The momentary contact push button Flicker On/Off switch toggles the OMNI mode between
bypass function (no added impedance) and flicker function (IEC 555-3 impedance). Lamps
above the switch indicate the selected mode.
NOTE: To prevent damage to the OMNI unit, the BYPASS mode must be selected when
the power source is operated on low output voltage range or if currents in excess
of OMNI ratings will be drawn.
Bypass relays are provided to short out the OMNI impedance so that the power source may be
used with its normal low output impedance or whenever the load current will be in excess of the
OMNI maximum current rating. When the BYPASS mode is selected, the OMNI impedance is
shorted out. When the FLICKER mode is selected, the OMNI impedance is added to the power
source output impedance.
Select the BYPASS position when low power source output impedance is required or desirable.
This is the case for most tests other than IEC 555-3 flicker tests. Also select the BYPASS
position when the power source is operated on the low voltage output range. The low voltage
output range can deliver currents well in excess of the OMNI maximum current rating.
