The sensor plate is isolated after the end of charging if the charged voltage reaches④
to the enough voltage. The plate voltage will be decreased by airflow of ions from
the ionizer. The internal discharge timer will start when the plate voltage reaches
1,000 volts. At this time, each bar of the bar graph corresponds to the time of1/10
between the measurement time.
The timer will stop when the plate voltage reaches the setting voltage default(
setting is 100 V . Then the timer measures the time from start to stop. The display)
shows the discharged time decay time in seconds after the end of the setting()
time.
