Measurement conditions

SW21, 42, 46 ; B

Measure I21 and 42 when V21 and 42 are 7.5V and 10.5V.

SW22 ; B

Measure I22 when V22=0V.

SW26 ; B

Vary V26 between 0~13V and measure

V26 when T27 phase inverts.

SW26 ; B

Measure I26 when V26=0 and 13V.

SW28 ; B

Measure I26 when V26=9 and 12V.

SW34 ; B

Measure I34 when V34=11V.

SW39 ; B

Measure I39 when V39=1V.

Vary T40 voltage from 0 5V and measure

the voltage when T27 phase inverts.

Measure I40 when V40 is 0V.

SW43 ; B

Measure I43 when V43 is 0.5V and 4.5V.

Measure I46 when V46=1.7V.

Measure I35 when V35=VCC2

SW2~4, 47 ; B, T2~4 ; SG3

Adjust V46 so that T29, 31 and 33

amplitude is 8V. Vary V47 voltage from

0 5V and measure V47 when T29, 31

and 33 sine waves disappear.

SW47 ; B Measure I47 when V47=0V.

SW2~4, 34, 43 ; B, T2~4 ; SG5

Adjust V43 so that T29, 31 and 33 amplitude is

3V. Vary V34 voltage from 3 6V and measure

the amount of T29, 31 and 33 voltage change.

SW2, 3, 4, 39, 43 ; B, T2~4 ; SG5

Adjust V43 so that T29, 31 and 33 amplitude is

3V. Vary V39 voltage from 6.2 8V and measure

the amount of T29, 31 and 33 voltage change.

SW27, 28 ; B, T40 ; SG6

Adjust V28 so that T27 amplitude is 6V.

tT= tTHL-tTLH

SW29, 31, 33 ; B, T40 ; SG6
