Calibration

Thermo Fisher Scientific
Successful download of the calibration file resets the background
concentration to zero.
The calibration is stored as CAL.TXT in the following format:
Format
CALIBRATION DATA<CR><LF>
VER=xx.xx
<CR><LF>
<CR><LF>
<detector calibration>
<detector calibration>
END<CR><LF>
The detector calibration format is as follows (note: from 1 to 9 span gas
points are allowed):
ddd CALIBRATION:<CR><LF>
<CR><LF>

where:
ddd = detector type
"FID"
"PID"
aaaaaa = gas concentration, floating point, right justified,
leading spaces
uuu = concentration units:
"PPM", parts-per-million
"% ", percent
dd = day of calibration, 01-31
mmm = month of calibration, Jan-Dec
yy = year of calibration, 00-99
hh = hour of calibration, 00-23
mm = minute of calibration, 00-59
ss = second of calibration, 00-59
bbbbbbbb = detector reading for calibration gas, integer,
right justified, leading spaces
fffffffff = count status:
"OK ", no errors
"DET_OFF ", detector reading invalid
