Part 3: Repair Information
3.2 Full charging voltage adjustment
<Purpose>
To adjust the maximum charging voltage of the capacitors.
<Standard>
330 + 3V
<Tools>
* Transistor pack
Multi-meter (voltmeter)
<Adjustment Method>
1. Remove the rubber cap around the vertical bounce unlock button on the
flash head, and bleed the main capacitor. (For details on how to bleed the
capacitors, see page 3-1.)
2, Connect the transistor pack to the flash battery contact, and apply a voltage
of 5.8V.
3. Turn the main switch on to start charging.
4. Read the voltage of the main capacitor when charging has finished, and
adjust VR-1 so that the voltage becomes 330+3V. (Measure the same
location as when bleeding the capacitors.)
