Section 3: Operation
1) The bar graph will never update faster than 1 Hz. If
the MPS is set to scan at a higher rate than this, the
data collected between the display refreshes are
ignored and discarded.
2) When the “Scan to Display” function is used, the
“FPS” variable is ignored. The MPS will continue to
scan and the bar graph will display data until the STOP
button is clicked no matter what the FPS variable is set
to.
3) The bar-graph automatically scales based on the
highest pressure value that is being displayed.
The size and scale of the “marks” in the bar graph can be
set by clicking “Set Bar Graph Mark.” This only effects how
the bar is displayed in the bar graph and has no effect on
the data or scaling of the graph.
Web Server: Calibrations & Validations
THIS FEATURE WILL BE RELEASED IN A FUTURE SOFT
-
WARE UPDATE.
Calibrations and validations of the MPS
can be controlled through the web server as well. The web
server’s calibration-validation interface makes setting up a
calibration and/or a validation much simpler than manually
setting up each of the individual parameters for the opera-
tion. It is accessed by clicking on the “Cal-Val” link in the
blue navigation bar.
Figure 3-12: Web Server Cal-Val Screen
The Cal-Val screen is broken up into three primary sections:
Temperatures, Pressures and Communications. The
“Temperatures” section includes several variables, each
duplicated to allow independent configurations for Calibra-
tions and Validations:
TEMPERATURE POINTS: This is used to set the number
of temperatures used during the calibration or valida-
tion. If the “temperature points” is set to 0, the MPS
will do a calibration/validation only at the module’s
current temperature and will not control the oven.
MINIMUM TEMPERATURE POINT: This is used to set the
lowest temperature point in the calibration/validation
MAXIMUM TEMPERATURE POINT: This is used to set the
maximum temperature point in the calibration/valida-
tion.
The MPS will use the minimum temperature and maximum
temperature and divide the spread evenly using the
number of temperature points to determine the tempera-
tures that the calibration/validation will be performed at.
The “Pressures” section includes several variables, each
duplicated to allow independent configurations for Calibra-
tions and Validations:
PRESSURE POINTS: This is used to set the number of
pressures that will be applied during the calibration or
validation.
MINIMUM PRESSURE POINT: This is used to set the
lowest pressure applied during the calibration/valida-
tion.
MAXIMUM PRESSURE POINT: This is used to set the
maximum pressure applied during the calibration/vali-
dation.
The MPS will use the minimum pressure and maximum
pressure and divide the spread evenly using the number of
pressure points to determine the pressures that are applied
to the module during the calibration/validation.
The “Communications” section includes parameters for
establishing a connection between the MPS, the pressure
calibrator and the oven (if applicable):
IP (OVEN): Sets the IP address of the oven controller.
PORT (OVEN): Sets the port number of the oven
controller.
DWELL (MINUTES) (OVEN): Sets the dwell time, in
minutes to allow the oven to stabilize at a temperature
after setting the temperature.
IP (CALIBRATOR): Sets the IP address of the pressure
calibrator.
PORT (CALIBRATOR): Sets the port number of the pres-
sure calibrator.
NUMBER (CALIBRATOR): Sets the channel number of the
calibrator being used.
DWELL (SECONDS) (CALIBRATOR): Sets the dwell time,
in seconds to allow the calibrator to stabilize at a
pressure. If this is set to 0, the MPS will query the
calibrator to determine stability and advance as soon
as the calibrator is stable.
Across the top of the screen is a bar with several links/
options. These features allow you to start and stop a cali-
bration, as well as interface with the module to retrieve the
latest validation report, download a copy of the calibration
