Section 6. Manual mode measurement 6.1 Ground connections During measurement of the ionizer performance, the accuracy might be affected by the static charge on the person and objects of circumference. Ground the person using a wrist strap etc. EA-5J must be also grounded by connecting a grounding lead to the ground terminal on EA-5J.

CAUTION In the decay time measurement, it is necessary to apply DC high voltage to the plate. The voltage should be 1,000 V or higher. If the insulation resistance of the sensor plate is low by dirt or short circuit of conductive lint such as hair etc., it is not reached to the enough voltage then the red LED, HV OUT lights continuously.
Page 25
The sensor plate is isolated after the end of charging if the charged voltage reaches ④ 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.
Page 26
CAUTION The timer starts when the plate voltage reaches 1,000 volts and it stops when the plate voltage reaches the setting voltage. If there are insufficient ions because of the ionizer failure etc., the timer cannot stop by the fact that the plate voltage does not reach the setting voltage.
Section 7. Auto mode measurement 7.1 Ground connections During measurement of the ionizer performance, the accuracy might be affected by ① the static charge on the person and objects of circumference. Ground the person using a wrist strap etc. EA-5J must be also grounded by connecting a grounding lead to the ground terminal on EA-5J.
