3.  OPERATION

(3) Sensor Trim for Static Pressure

For the EJX differential transmitters, zeroing and full
sensor trim of the static pressure is performed in the
same way as with the primary process variable (PV).
Note that the static pressure sensor trim should be done
only after trimming the PV.

(4) Reset Trim Adjustment to Factory Setting

The 

Clear P snsr trim

 and 

Clear SP snsr trim

commands can reset the trim adjustment to the initial
calibrated values that were set. The amount of the
adjustment by the external zero-adjustment screw is
returned to the initial setting as well.

Trim Analog Output

Fine current output adjustment is carried out with 

D/A

trim

 or 

Scaled D/A trim

.

• 

D/A Trim
D/A trim

 is to be carried out if the calibration digital

ammeter does not exactly read 4.000 mA and 20.000
mA with an output signal of 0% and 100%.

• 

Scaled D/A Trim
Scaled D/A trim

 is to be carried out if the output is

adjusted using a voltmeter or a meter whose scale is
0 to 100%.
