Operation
Model 287A performs manual or automatic
decay and balance tests for periodic verification
of ionization equipment. It then stores the results
and averaged decay times for up to ten manual
tests and up to ten complete automatic test
sequences.Temperature and relative humidity
are displayed real-time and recorded with the
test data.
All instrument functions are controlled by four
pushbuttons
In DECAY mode a built-in high voltage
generator charges the plate to over 1050 volts.
During testing the plate will discharge toward
zero in the presence of ionization. The elapsed
time of decay between 1000 volts and 100 volts
is displayed.
In the BALANCE mode, isolated plate voltage,
test duration and + and - peak voltages are
displayed.
Self-tests include battery check and tests for
functional errors.
