the calibration code listed on the old box to the calibration code listed on
the new box.
a. If the calibration codes match, there is no need to do anything else.
b. If the calibration codes do not match, you must either perform a
TUBE CAL using a tube from the new box (see “Performing a TUBE
CAL” on page 241) or you must enter the new calibration code into
CAL CODE (see “Entering a CAL CODE” on page 248), depending
on what method of calibration you used with your old box of filter
tubes. See “Calibrating the 10.0 eV/Benzene PID Sensor” on
page 239 for a description of calibration methods.
