4. Enter the new value for the offset in the Offset field and the new
value for the calibration factor (gain) in the Factor field. If you do
not want to change either the offset or the gain, leave that field
unchanged.
The Factor parameter has sensor-dependent use. It affects the gain
of the measurement or the sensitivity of the radiation sensors. To
calibrate radiation sensors QMN10x and QMS10x with the QML
logger, enter the sensor-dependent sensitivity factor
[V/Wm
-2
], which is given in the type sticker or calibration sheet of
the particular sensor. To calibrate other listed sensors, enter the
gain of the measurement, that is, the slope of the conversion curve.
5. Calibrate the sensor by selecting Calibrate.
NOTE The values you have changed in the Manual Calibration window but
have not yet sent to the QML logger by selecting Calibrate are
displayed in bold. You can obtain the current Offset and Factor values
again from the QML logger by selecting the Refresh button.
