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.
