This function is used to select the calibration point which will be entered.
Further options:
• "1" to "9": calibration points for various densities
• "10": recalibration point. Once the calibration point has been entered, I
0
is recalculated
according to the current measuring conditions. The absorption coefficient µ from the
original calibration remains unchanged. Calibration point "10" can be entered if the
measuring conditions have changed, e.g. as a result of deposit buildup in the measuring
tube.

Stop/edit
Start
This function is used to start automatic entry of the selected calibration point.
Options:
•
Stop/edit
This option must be selected if:
– The calibration point is not to be entered (e.g. because it has already been entered).
The pulse rate of the calibration point is then displayed in the following function
"Density calib." (*1B)
. This value can be changed if required.
– The calibration point is to be entered manually. The Gammapilot M changes to the
"Density calib." (*1B)
function.
•
Start
This option is used to start automatic entry of the calibration point. The Gammapilot M
then changes to the
"Avg. pulse rate" (*11)
function.
"Avg. pulse rate" (*11)
Local display
Avg. pulse rate *11
1983 cps
The average pulse rate is displayed with this function (after the selection of "Start" in the
previous function). Initially, this value fluctuates (because of the decay statistics), but
reaches an average value over time due to integration. The longer the averaging is
performed, the lower the fluctuations.
