OPERATION
Performing Ionizer Tests
Initiate automated test sequences and manual tests directly from the system prompt, -.-.
Selecting a Manual Test: Press +Decay to start a positive discharge test.
Press -Decay to start a negative discharge test.
Press Bal to start a balance (offset voltage) test.
The respective indicator is on and flashing while a test is in
progress.
The respective indicator is on and not flashing when the test is
complete and data is available.
Manual Zero for the Plate: In the event that the instrument does not indicate zero volts for
a balance test (when the ion collecting plate is hard-grounded),
the fieldmeter can be zeroed by pressing the
Bal button for >2
seconds. This would be done from the system prompt, -.-.
Selecting an Automated
Test Sequence: Press Auto to run a sequence of discharge and balance tests.
Cancelling a Test: Press Shift/Cancel to cancel a test after it is started.
To View Test Results: Test results are displayed after each test.
For a Decay test, the Decay time is displayed until a new
button is pressed. In the instance when a decay test fails, such
as if there is no ionization to reduce the plate voltage, a failure
message is displayed: either
+DCY DFAI or -DCY DFAI,
depending on the polarity of the decay test.
For a Balance test, the display scrolls through the negative
peak voltage (
VMIN), the positive peak voltage (VMAX) and the
average voltage ( AVG).
Press
+Decay, -Decay, Bal or Auto to start a new test or
sequence of tests.
Press Shift/Cancel to return to the system prompt -.-.
Test data can also be viewed using the ReCall feature of the
Model 300.
