If the gauge is equipped with an analog output, the range of the
output is automatically calibrated to match the tank calibration (G
and R). If you want to change this setting, do the following:
• Enter Source. Available options are: level, level rate, ullage,
signal strength and volume.
• Enter the analog output values that correspond to 4 mA and 20
mA, respectively.
• Select Alarm mode.
- Select High if you want the analog output to lock on a value
higher than 20 mA when an error is encountered.
- Use Low if you want it to lock on a value below 4 mA.
- The Hold Last option freezes the analog output to the current
value when an alarm is triggered.
• DA Trim. Use this option to calibrate the Digital/Analog Converter
to correspond to the nominal values 4 mA and 20 mA.
Note! The analog output is set to fixed current mode during the
calibration procedure.
To calibrate the DAC do the following:
1 Choose the D/A Trim option.
2 Click the OK button if you want to continue, (or click the CNCL
button to quit without calibrating the D/A converter).
Response: the analog output is set to 4 mA.
