How to Check Idling Current
a. Idling Pre-check
Channel
D
Terminals
*Connect 1/4W 100 ohms resisters in each probe of multi mater .
*Make sure from 1mV to 21mV, When it is not this range, you have to make sure again repair.
b. Aging
The AVR is turned on about 6 minutes for aging.
C
c. Idling After-check
*Equip series 1/4W 100-ohm resisters near the terminal respectively in each pole of the jig used for the above mentioned terminals.
*If the measured value are under 1 mV or over 21 mV, turn off the power of the AVR and rework the AVR.
*Connect 1/4W 100 ohms resisters in each probe of multi mater .
*Make sure from 1mV to 21mV, When it is not this range, you have to make sure again repair.
