2. CALIBRATION ROUTINES
This routine will use a two point (low-hi) method to calculate the calibration constant
and dead time of the detector. The following display will appear when performing the routine.
L CAL 0.000e+00
H CAL 0.000e+00
LOW CAL POINT?
LO SMPL 0
HI SMPL 0

CALIBRATION CONSTANT/DEAD TIME ROUTINE DISPLAY
A. INFORMATION PROMPT: Prompts the user for the parameters required for the routine.
When the routine is first started the prompt will prompt the user low calibration point. Once
entered it will prompt for the following parameters in order.
HI CAL POINT
TAKE BACKGROUND
TAKE LOW SAMPLE
TAKE HI SAMPLE
SAVE NUMBERS?
B. RATEMETER BARGRAPH DISPLAY: A logarithmic display of the ratemeter reading in
cps.
C. L CAL: Identifies the low calibration point that will be used in the routine.
D. H CAL: Identifies the high calibration point that will be used in the routine.
E. LO SMPL: Shows the reading obtained from the low sample source.
F. HI SMPL: Shows the reading obtained from the high sample source.
NOTE: Line 1 will indicate the ratemeter reading when a sample is being taken,
and lines 3 and 4 will show the scaler taking a count. When the routine is
complete Line 3 will display the calculated calibration constant, and line
4 will show the calculated dead time constant. These numbers will be
saved into the active detector setup if the user answers yes to the prompt
to save the numbers.
