※１：The distance between the charged object and ionizer is 300mm or more. With air purge.
※２：When the potential of the charged object is measured with the feed back sensor, the relation
between the charged potential and the sensor-monitor-output-voltage and the sensor detecting
range will vary depending on the installation distance between the ionizer and sensor.
