Electronic Flow Sensing
Electronic flow sensor (EFS) calibration
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:
CLEAR
.
2 
ENTER
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 
B 
.
2. Enter the desired gain calibration value, preceded by 
- 
:
- 
Numeric Value 
ENTER
- 
is necessary to signify entry of a gain calibration value, rather than a measured flow rate.
3.Press 
ZERO 
: FLOW A ZERO is displayed, followed by a value (the 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 
B 
.
4.Enter the desired zero calibration value:
Numeric Value 
ENTER
Note that alternately pressing
ZERO 
or 
FLOW 
displays either the zero calibration value or the gain calibration value for the given channel (A or B).
