Gauge Info tab — additional display values
Uniformity Gain Displays the current value of the uniformity gain. Use this
to force all density gauge sensors to output the same
counts at a given radiation field
Source Decay Gain The current value of the source decay gain. Use this to
compensate for the natural decay of the radiation source,
which produces a lower field over time.
Stdz Gain The current value of the standardize gain that adjusts with
each standardize procedure.
HV Setting The set point for the sensor high voltage.

Sensor Coefficients
T0 – T3
Value Description
Sensor
Coefficients The algorithm that compensates for variations in measurement
output with changes in temperature uses temperature
coefficients. The factory determines the coefficients through
rigorous testing. You cannot change them through normal
operation.
