MEASUREMENT METHOD
1) Set pin 17 to open, connect a 1-kΩ resistor to the pin, and apply 3V to
the pin from the power supply.
2) When the subaddress (11) data are set to (10), (30), (50), and (70),
measure from the waveform of pin 17 the current flowing to GND during

(I19a, I19b, I19c I19d )
1) Connect TP13 to TP13b ; TP14 to TP14b ; TP15 to TP15b.
2) Set SW₂₀ to b.

4) By referring to Figure 1 of T₄₃, determine the voltage output from pins
13, 14, and 15 (IKR, IKG, IKB) during the ACB pulse input to the signal
input to pin 20.
