Easy to use
Now it’s simple to make sure any ionizer is
doing its job.
Go/no-go check
1. While away from any ionized airflow, turn the
Model 282 fieldmeter on and check “zero”
reading.
2. Slide the plate assembly onto the Model
282 fieldmeter.
3. Select charger polarity by grounding the
opposite terminal. (Ground “-” to select “+”).
4. To charge the plate adapter, place it in contact
with the appropriate charger terminal.
5. Position the fieldmeter with the plate adapter
in the ionizer airflow. The meter should
rapidly drop from 1100 V to zero.
Note: All tests should be performed while
wearing a wrist strap to ensure a proper ground.
Decay rate check
Follow the steps above, but connect the
fieldmeter to chart recorder, or use a stopwatch
to measure the time required for the voltage to
decay from ±1.00kV to ±0.10kV.
Balance check
Turn on the fieldmeter with the plate adapter
attached. Point it into the ionizer airflow, check
for an average reading of zero.
An offset reading indicates an unbalanced
ionizer.
