Connect an ammeter between #23 and GND.
Measure the current.
Measure the TP26 waveform peak value. (V
Set the subaddress (06) D
Set #25 to open. Connect an external power supply to #25. Decrease the voltage from 5 V. When full blanking is applied to #13, measure
the voltage.
Connect a 5-V external power supply to #23. Read D
When the external power supply connected to #23 is disconnected, read D
Ensure that an E / W waveform is output from #22. (V
Connect a 9-V external power supply to #24. Read D
When the external power supply connected to #24 is disconnected, read D
Ensure that a V-out waveform is output from #25. (V
