23.0 CALIBRATION OF TRANSDUCERS
Connect the computer cable from the computer to the DB9 port #1 on the back of DE-2500
display module.
Using the DE-2500 software resident on the CDROM, open the DE-2500 program. Then click
on the “CALIBRATE” button at the top of the screen.
Select the number of channel to be calibrated.
The sensor selection box will show either the default value or the past calibrated value
depending the firmware version of the DE-2500.
Under the “CALIBRATION SETPOINT” section you will find a box that reads “CURRENT
DATA”. This is the actual information being displayed on the DE-2500 Display.
On the Terminal Board connect a voltmeter between the (+) and (-) transducer output
terminals for the channel being calibrated.
Apply the desired minimum pressure or temperature to the transducer being calibrated. Next
take note of the voltage being measured on the voltmeter, this voltage is to be entered in the
“LOW SENSOR VOLTAGE” box. Then click the “ACCEPT” key to enter the new low value.
Increase the pressure or temperature to the desired high reading of the transducer being
calibrated. Again take note of the voltage being measured and enter the measured voltage
in the HIGH SENSOR VOLTAGE” box and hit accept.
Your calibration of that channel is complete.
