Explanation
Calibration Data File
The pressure transmitter calibration data before and after adjustment is saved to CSV files.
File Name
Calibration data before adjustment: MSxxF_y.CSV
Calibration data after adjustment: MAxxL_y.CSV
xx: 00 to 99 (calibration group number)
Same number between the calibration data file before and
after adjustment
y:
0 to 9 Sequence number for calibration data files before
adjustment or after adjustment
Because the number xx is the same for calibration data files before and after adjustment, the
association is maintained.
If you change the device information or calibration procedure, the number xx is incremented.
Note
• If there are gaps in the calibration group numbers due to the deletion of files and the like, precedence is
given to the missing numbers.
• If all the calibration group numbers or file sequence numbers are used up, an error will appear. Copy the
necessary files to another location, and delete them.
Data That Is Saved
Calibration conditions, device information, date and time of calibration, pressure transmitter input
(source) value at each calibration point, pressure transmitter output (measure) value, error (%), and
judgment result are saved.
Judgment Result
If the pressure transmitter output value is within the tolerance set in section 3.3, PASS is displayed and
saved. Otherwise, FAIL is saved.
