indicate a positive or negative charging voltage
(1.1kV minimum). If a voltage of less than
±1.1kV is displayed, check to see if the low
battery indicator on the 3M
illuminated. If illuminated, replace the battery
in the charger. If the unit continues to supply
an incorrect voltage to the charge plate, please
contact 3M for additional instructions.
4.3 Testing ionizer discharge time: after charging
the plate, hold the 3M
approximately one foot (30.5 cm) away from the ionizer. Monitor the
display to see how quickly the 1.1 kV charge is dissipated to 0.1 kV. The
speed at which this occurs (the discharge time) indicates how well the
ionizer is operating. Please refer to the specific ionizer's operating manual
or consult with the ionizer manufacturer to determine what this discharge
time should be. Repeat this procedure for both a positively and a negatively
charged plate.
4.4 Testing ionizer offset balance: zero
the charge plate by touching it with a
grounded object. This can either be the
finger of a grounded person or some other
item which is connected to electrical
ground. In either case, zeroing the charge
plate should make the display on the
Static Sensor 718 read zero. Hold the
Static Sensor 718 approximately one foot
(30.5 cm) in front of the ionizer. Monitor the display. The value displayed is
the offset balance of the ionizer, which is the difference between the number
of positive and negative ions being emitted. Please refer to the specific
ionizer's operating manual or consult with the ionizer manufacturer to
determine what this offset balance should be.
5.0 Service/Calibration
5.1 Service and Repair: in the event that you believe the Static Sensor 718 or
the 3M
Air Ionizer Test Kit 718A is in need of repair, please contact your
