Entering specific ZERO and GAIN values

Calibration values for zero and gain should be recorded when a
particular channel is calibrated. They can then be reentered through the
keyboard if necessary, without repeating the entire calibration procedure.
To enter specific zero and gain calibration values:
1. Select CALIB AND TEST mode, function 2:
GAIN A (or GAIN B) is displayed, followed by two values (the observed
flow rate through the channel and the current gain calibration value
for the channel).
Note that Channel A is assumed by default. If Channel B is to be
calibrated instead, press
2. Enter the desired gain calibration value, preceded by
than a measured flow rate.
3. Press
current zero calibration value for EFS Channel A).
Note that Channel A is assumed by default. If Channel B is to be
calibrated instead, press
4. Enter the desired zero calibration value:
Note that alternately pressing
calibration value or the gain calibration value for the given channel (A
or B).
