ranges.
3. [Oponal] 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 me for the modules to reboot.
4. Make all necessary pneumac connecons to the
MPS, including:
• Calibrator posive output to the CAL port.
• Calibrator negave output to the REF port.
Note: this requires a manifolded connecon to all 32
inputs, or the calibraon 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. [Oponal] For mulple module calibraon/valida-
ons, 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 connuing.
A Field Calibraon (single or mul-unit) will apply dened
pressures from the calibrator in equal steps, at the current
temperature of the module(s). This calibraon create
correcon terms that are used across the full compensated
range (0°-70°C). A validaon is typically required aer a
calibraon. The eld calibraon coecients can be enabled
or disabled at any me using the FCENABLE variable.
1. Follow the steps under Setup and Conguraon.
2. [Oponal] If a calibraon log is required (for trouble-
shoong or requested by Scanivalve), start an ASCII
capture le using ScanTel:
File > Start ASCII Capture
Name the le and save in a directory.
3. To start an automated single unit eld calibraon,
issue the command:
CAL F<ENTER>
To start an automated mul-unit eld calibraon, issue
the command:
MCAL F<ENTER>
The Field Calibraon (single or mul) will begin. The
process will stream informaon 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 nd the error and correct any noted errors.
4. Once a Field Calibraon is complete, the eld coef-
cients are stored in LIST FC. The eld calibraon
process will automacally enable the eld coecients
in all modules (SET FCENABLE 1). To save these coef-
cients, 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).
A Field Validaon (single or mul-unit) will apply pres-
sures from the calibrator at the current temperature of
the modules, compare the EU readings to the calibrator
readings, and nd the percent error of full scale. This will
validate the current coecient table in the MPS module.
This can be performed with or without eld calibraon
coecients (FCENABLE).
1. Follow the steps under Setup and Conguraon.
2. [Oponal] If a validaon log is required (for trouble-
shoong or requested by Scanivalve), start an ASCII
capture le using ScanTel:
File > Start ASCII Capture
Name the le and save in a directory.
3. To start an automated single unit eld validaon,
issue the command:
VAL F<ENTER>
To start an automated mul-unit eld validaon, issue
the command:
MVAL F<ENTER>
The Field Validaon (single or mul) will begin. The process
will stream informaon 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 nd the
error and correct any noted errors. If there is an issue,
check the log to nd the error and correct any noted errors.
4. Once the validaon is completed, the report can be
found on the MPS’s system memory. Open “Windows
Explorer” and in the address bar, type:
