Note 1. Measurements are made for each of 1ch, 2ch, 3ch using input A and input B.
Input A: VCTL (pins 10, 13, 15) is 12 V at the measurement mode.
Input B: VCTL is 0 V at the measurement mode.
2. Measurements are made using input A and B.
3. Measurements are made for 1ch, 3ch.
4. Measurements are made for each of 1ch, 2ch, 3ch using input A and B on other channels.
