ADJUSTMENT OF IDLING CURRENT
[NOTES]
1. Set R6040
6046 to minimum position before POWER ON.
2. Equip series 1/4W 100-ohm resisters near the terminal respectively in the each poles of the jig used for
P6080-6086 terminals.
[PROCEDURES]
1. Set the voltages at P6080
6082 to 2.5mV by adjusting R6040
6042, under the condition of
no input and no load, immediately after POWER ON.
2. Set the voltages at P6083
6086 to 1.5mV by adjusting R6043
6046, under the condition of
no input and no load, immediately after POWER ON.
3. Re-adjust by following procedure after
4 6
minutes of heat running.
Below 9mV 9mV Below 6mV 6mV
Between
