Stop measurement by pressing the <run> button again.
Accept result with <enter>. Cursor jumps to next row.
Enter the density value of the sample(s) determined in the lab in g/cm
3
and confirm with
<enter>. Cursor jumps to third row.
Push <enter> to confirm current product temperature.
Proceed in the same manner for the other rates. Rates that are not used must contain
“0”. If “0” is already there, press <more>. Otherwise, delete values with <clear> and
confirm each with <enter>.
Push <sk2> to select Calculate.
Select calibration mode according to the number of entered value pairs (lin for 2, squ for
3 and cub for 4 and more value pairs; if you chose auto, the program automatically se-
lects the best calibration mode. Prerequisite: 4 value pairs).
Upon confirmation with <enter>, calibration is carried out and the calculated
coefficients can be viewed.
The program calculates the linear absorption coefficient and displays it as Result a1.
The calculated zero count rate I0 is displayed.
Depending on the selected calibration mode, the program calculates the following coeffi-
cients and displays them:
Coefficient a1, a2, a3 and the square error
If necessary, enter a factor for multiplicative correction of the measured values.
If necessary, enter an Offset for additive correction of the measured values.
Display of temperature-corrected density values.
Push <done> to return to submenu group.
Push <run> to start the measurement.
Calibrate once more if current output limit value changes (see page 22).
