This screen provides the options and indications needed to default, verify, and calibrate the filter

The E-BAM field is the current value of the chosen Filter Sensor.
The Standard field is the field where the value shown on the traceable reference standard is
entered if the E-BAM value needs to be adjusted. To make a change, press the green bordered
value box and the numerical entry keypad (Figure 3-5) will be displayed. Enter the value currently
shown on the standard and press the OK key to set it. Press the CALIBRATE key to set any
changes. The E-BAM and Standard fields should now match.
The DEFAULT key can replace the current calibration factors with the factory default settings on

key to set that specific sensor back to factory values and then try the calibration again.
