The detector calibration format is as follows (note: from 1 to 9 span gas
points are allowed):

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
