Comments
Calculated by instrument and depends on front panel
Temperature and Pressure settings.
Electrical charge delivered to readout in response to
radiation incident upon detector since the last
exposure.
The sum of all charge accumulated due to exposures
since the RESET/MEASURE button was last pressed.
The sum of all accumulated charge not including the
current exposure since the RESET/MEASURE button
was last pressed.
Factory calibrated electrical charge.
Calibrated electrical charge.
Calibrates the charge measured by the electrometer.
Viewed on a Test Function screen.
The electrical charge measured when no incident
radiation is present.
Calibrated electrical current.
The constant electrical current required to accumulate
charge Q over time TStart to T.
Values are field programmable via Customization
Software.
The electrical current measured when no incident
radiation is present.
Calibrates the current. Viewed on a Test Function
screen.
Specifies the number of seconds the rate divisor is
equal to 1(s), 60(min), 3600(hr).
The time corresponding to Q and I.
The time required to accumulate charge QExposure
with a constant electrical current IAvg.
The time corresponding to QOffset and ILeakage.
The electrical charge delivered during the timer
interval.
The total amount of timed charge that should be
accumulated at the completion of the timer interval,
based on the observed delivery rate.
