CALIBRATION MODE

Calibration mode allows the user to calibrate the analog inputs such as differential

pressure, pressure, and temperature. While operating in the calibration mode, the RTU

continues to periodically update volume. The analog input value used for calculations is

the value measured when calibration mode was initially entered. Once in calibration

mode, the user can perform the following operations:

 Calibrate zero only.

 Calibrate span only.

 Calibrate both zero and span.

Of course, the option to change the calibration reference points is available at all times.

Several other features make the software calibration routine attractive and more

intuitive. In the RTU, unit calibration is software-based; there is no need for laborious

operator adjustments. Software calibration does away with the need for repetitive

potentiometer adjustments, thereby simplifying field calibration procedures.

Calibrating Field Transmitters

1. Display the value of the transmitter to be calibrated on the display. The function

keys can be used for quick access.

2. Press the blue cal key. Enter your password at the optional PASSWORD? prompt,

if required.

3. The RTU will enter calibration mode. The display will alternate between

CALIBRATING and the parameter label; PRESSURE #1 for example.

4. Apply the appropriate zero reference to the transmitter and wait for the reading to

stabilize.

5. Press the blue zero key. The display now shows the following:

ZERO> XX.XX

NEW?>

Where XX.XX represents the unit's default zero value. If the current zero

NOTE

Pressing esc repeatedly from anywhere within the calibration procedure will back the operator

out of calibration mode.
