Measuring Capacitance
Verify that the capacitors are fully discharged
. Follow the steps in the “High Voltage
Danger” section before attempting to measure capacitance.
Set your meter to measure
capacitance. Touch one meter lead to each terminal of a
capacitor. The meter may take several seconds to complete the reading. The IPS-3400
strobe lights use five 70uF capacitors for the Day bank. That means you should measure
about 350uF since the capacitors are wired in parallel.
The night capacitor must be measured separately and should read about 3uF. Remove
all wires from one terminal of the capacitor to keep other circuitry from interfering with the
measurement.
