this capacitor creating a high current pulse that is sent to the flash head. In the flash
head the trigger pulse is stepped up by 1000 times to about 20KV and applied to the flash
tube.
Measuring High Voltage
Measuring Side Light Voltage
Set your meter to measure
AC Voltage
.
Touch the black meter lead to the chassis of the strobe light. Touch the red meter lead to
terminal 8 on TB1. Put the strobe light in night mode using the Day Night Switch on the
Trigger Board.
Your meter should indicate about 120VAC.
Measuring Side Light Current
Use clamp-on type current meter to read
AC Current
around wire connected to terminal 8
on TB1. Put the strobe light in night mode using the Day Night Switch on the Trigger
Board. Your meter should indicate about 1Amp for each side light burning.
Set your meter to measure
DC Voltage
.
Touch the
BLACK
meter lead to the
chassis of the strobe light. Touch
RED
meter lead to terminal 1 on TB1. The
meter should indicate approximately
500VDC (450 to 550 typical).
