ranges.
3. [ Optional] If MCAST is altered, a SAVE <ENTER>
and power cycle if required. Issue the SAVE <ENTER>
command and wait for the save to complete. Once the
prompt (>) is returned, issue the command:
REBOOT <ENTER>
Disconnect and close all instances of ScanTel that are
open and allow time for the modules to reboot.
4. Make all necessary pneumatic connections to the
MPS, including:
• Calibrator positive output to the CAL port.
• Calibrator negative output to the REF port.
Note: this requires a manifolded connection to all 32
inputs, or the calibration input header (PN 20080)
Leak checks, or trap and decay tests, and pressure
response should be performed on both the CAL and
REF port to ensure correct plumbing, and that there
are no leaks present.
4. Connect to a single MPS4200 using ScanTel (or similar
program).
5. [Optional] For multiple module calibration/valida -
tions, issue the command:
MFIND <ENTER>
Ensure that all expected modules respond.
If they do not, please check that all module’s MCAST
variables match before continuing.
Performing a Single or Multi-Field Calibration
A Field Calibration (single or multi-unit) will apply defined
pressures from the calibrator in equal steps, at the current
temperature of the module(s). This calibration create
correction terms that are used across the full compensated
range (0°-70°C). A validation is typically required after a
calibration. The field calibration coefficients can be enabled
or disabled at any time using the FCENABLE variable.
1. Follow the steps under Setup and Configuration.
2. [Optional] If a calibration log is required (for trouble -
shooting 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,
issue the command:
CAL F <ENTER>
To start an automated multi-unit field calibration, issue
the command:
MCAL F <ENTER>
The Field Calibration (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.
4. Once a Field Calibration is complete, the field coef -
ficients are stored in LIST FC . The field calibration
process will automatically enable the field coefficients
in all modules ( SET FCENABLE 1 ). To save these coef -
ficients, the 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 Single or Multi-Field Validation
A Field Validation (single or multi-unit) will apply pres -
sures from the calibrator at the current temperature of
the modules, compare the EU readings to the calibrator
readings, and find the percent error of full scale. This will
validate the current coefficient table in the MPS module.
This can be performed with or without field calibration
coefficients ( FCENABLE ).
1. Follow the steps under Setup and Configuration.
2. [Optional] If a validation log is required (for trouble -
shooting 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 validation,
issue the command:
VAL F <ENTER>
To start an automated multi-unit field validation, issue
the command:
MVAL F <ENTER>
The Field 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. If there is an issue,
check the log to find the error and correct any noted errors.
4. Once the validation is completed, the report can be
found on the MPS’s system memory. Open “Windows
Explorer” and in the address bar, type:
