Third Buffer Value (does not appear if automatic buffer recognition is used)
Enter the value of the buffer being used
Rinse Electrode
Remove the sensor from the process, rinse it off, and place it in the buffer solution. Touch Confirm when
ready.
Stabilization
When the temperature (if applicable) and signal from the sensor is stable, the controller will automatically
move to the next step.
Cal Successful or Failed
If successful, touch Confirm to put the new calibration in memory. The calibration adjusts the offset, gain
(slope) and calibration midpoint and displays the new values. If failed, you may retry the calibration or
cancel. Refer to Section 7 to troubleshoot a calibration failure.
Resume Control
Replace the sensor in the process and touch Confirm when ready to resume control.
One Point Analog Calibration
OK to disable control? Touch Confirm to continue or Cancel to abort.
Input Value
Enter the mA value that the transmitter will be sending. Touch Confirm to continue or Cancel to abort.
Please set input signal to specified value
Make sure that the transmitter is sending the desired mA signal. Touch Confirm to continue or Cancel to
abort.
Automatic circuit calibration in progress
Cal Successful or Failed
If successful, touch Confirm to save calibration results. The calculated offset will be displayed.
If failed, you may retry the calibration or cancel. You may also restore calibration to the factory defaults.
The calibration will fail if the measured mA is more than 2 mA away from the Input Value entered.
Please restore input signal to process value
Put the transmitter back into normal measurement mode if necessary and touch Confirm when ready to resume
control.
Two Point Analog Calibration
OK to disable control? Touch Confirm to continue or Cancel to abort.
Input Value
Enter the mA value that the transmitter will be sending. Touch Confirm to continue or Cancel to abort.
Please set input signal to specified value
Make sure that the transmitter is sending the desired mA signal. Touch Confirm to continue or Cancel to
abort.

Second Input Value
Enter the mA value that the transmitter will be sending. Touch Confirm to continue or Cancel to abort.
Please set input signal to specified value
Make sure that the transmitter is sending the desired mA signal. Touch Confirm to continue or Cancel to
