3.3 Setting the Device Information and the Calibration Conditions of the Pressure Transmitter
Explanation

Device Information

The device information that you set here is saved to a file along with the calibration data. This is
convenient in associating the saved data with the device.
Input Characters
The number of characters that you can enter is as follows.
Model No.: Up to 20 alphanumeric characters
Tag No.:
Serial No.: Up to 15 alphanumeric characters
Measurement Function and Source Function
The measurement function measures the output from the calibration target, and the source function
outputs the input to the calibration target. If you set the source function to pressure, the CA700 only
monitors the input to the calibration target.
The combinations of the measurement function and source function are as follows.
Measurement Function
Pressure (P)
Pressure (EXT P, External pressure
sensor)
Pressure switch (P SWITCH)
Pressure switch (EXT SWITCH,
External pressure sensor)
DC current (mA MEASURE)
Loop current (mA LOOP)
DC voltage (V MEASURE)
External pressure sensor type (EXT P or EXT SWITCH)
Fixed to 16 MPa.
Mesurement Range (EXT P or EXT SWITCH)
You can select the measurement range of the external pressure sensor.
Unit (Pressure)
You can select the pressure unit.
Averaging
The CA700 displays moving average results.
Scaling
The CA700 displays linearly scaled results. You can assign a unit appropriate for the values after
scaling.
The scaling method is the same as pressure measurement. See section 2.1.
0% Value and 100% Value
Set the 0% and 100% of the calibration range in terms of the calibration target input and output (which
corresponds to the input).
