Drag and drop (or copy and paste) the RptXXX.csv to the
desktop for viewing. This must be repeated for every
module that was validated.
Performing a Single or Multi-Field Calibration-Valida-
tion
A Field Calibration-Validation (single or multi-unit) will
apply pressures from the calibrator at the current tempera-
ture of the modules, create and enable the field calibration
coefficients, and then auto-perform a validation. This
process allows for a single command to start a calibration
and validation without additional user input.
1. Follow the steps under Setup and Configuration.
2. [Optional] If a calibration-validation log is required
(for troubleshooting or requested by Scanivalve), start
an ASCII capture file using ScanTel:
File > Start ASCII Capture
Name the file and save in a directory.
3. To start an automated single unit field calibration-
validation, issue the command:
CALVAL F <ENTER>
To start an automated multi-unit field calibration-valida -
tion, issue the command:
MCALVAL F <ENTER>
The Field Calibration-Validation (single or multi) will begin.
The process will stream information to the screen. When
completed, the MPS will return a completed message,
followed by a Prompt (>). If there is an issue, check the log
to find the error and correct any noted errors.
The calibration process will automatically enable the
field calibration coefficients ( SET FCENABLE 1 ) before the
validation. Once a Field Calibration-Validation is complete,
the field coefficients are stored in LIST FC .
5. Once the validation is completed, the report can be
found on the MPS’s system memory. Open a window in
“Windows Explorer” and in the address bar, type:
FTP://<IP address of the MPS> <ENTER>
Drag and drop (or copy and paste) the RptXXX.csv to the
desktop for viewing. This must be repeated for every
module that was validated.
6. If the module passes validation; in ScanTel, issue the
command:
SAVE FC <ENTER>
Saving the FC terms must be repeated for every module
that was calibrated (connect using ScanTel and issue
the command).
Performing a Manual Field Calibration or Validation
If a manual calibrator is to be used (non-Scanivalve cali-
brator), repeat the steps as show in the procedures
above, however replace the “ F ” variable of the CAL/VAL
commands with “ FM ”. The MPS will start the commanded
sequence and will instruct the user to apply pressure
manually, and input the pressure reading of the calibrator
at each pressure point.
