• Adjustment method of VC PWM Duty (L)
(mode number: 762)
1. Select the manual mode of the test mode, and set the mode
number 762. (See page 13)
2. Connect a digital voltmeter to the AP913 (VC) on the MAIN
board, and adjust
[EASY SEARCH +] key (voltage up) or
[EASY SEARCH --] key (voltage down) so that the voltage
becomes 2.5 ± 0.02 V.
Proceed to the next step without pressing X key if voltage is
already adjusted.
3. Press the X key to write the adjusted value.
• Adjustment method of VREM PWM Duty (H)
(mode number: 763)
1. Select the manual mode of the test mode, and set the mode
number 763. (See page 13)
2. Connect a digital voltmeter to the AP913 (VC) on the MAIN
board, and adjust
