7.8 Procedure to Reset Calibration
SmartLine DE Pressure Transmitter can erase incorrect calibration data by resetting the device back
to final factory calibration, which is performed per the ordered range. The Corrects Reset command
returns the zero and span calibration factors to the original precise factory calibration.
The following procedure is used to reset calibration data to factory calibrated range using the
MC Toolkit.
1. Connect the MC Toolkit per Figure 6. Start the MC Toolkit application into operation such
that the DE MAIN MENU is displayed, and establish communication with the Transmitter.
2. From the DE MAIN MENU, click Calibration. The CALIBRATION menu will be
displayed.
3. Click Reset Corrects. The following prompt will be displayed.
4. Click No, if corrects should not be overwritten with factory values.
Click Yes, if corrects need to be overwritten with factory values.
The timer will appear briefly, indicating the operation is performed
This function commands the transmitter to overwrite all user input corrections with
factory default (characterization) values. It is intended for use only when excessive
corrections render the transmitter inaccurate. It is highly recommended that input calibration
procedure be performed after calibration reset.
