6.0 MICROCAL INTERFACE SCREENS
The MicroCal Interface is tab-based, split into 5 major sections at the bottom of the
screen.
6.1 APPLICATION DEFINITIONS
General: This describes operation for the broadest range of applications.
Dial Gauge: Departures from general operation for Dial Gauge calibration.
P-Switch: Departures from general operation for Pressure Switch calibration.
Expert System: Departures from general operation for Expert System calibration.
6.2 REAL TIME: GENERAL
Screen Instructions (Diagram 9):
Real Time page is constantly updating and is used to see the output and pressure being
applied for calibration purposes and test purposes (acts as a digital indicator).
APPLIED PRESSURE WINDOW: Displays system pressure. When a new pressure set point
is selected, the text will turn yellow while pressure is outside of target control band (Re-
quired control stability for UUT). Text will turn green when target pressure is reached.
SETPOINT: The go to pressure macro buttons are configured by the selected UUT pressure
range. These can be used to manually step through pressure setpoints for calibration or
when making manual adjustments. For all units, the top most button will display the
UUT’s -FS Pressure Value. The bottom-most button will display the UUT’s +FS Pressure
Value. Pressing any of the buttons enters the pressure value on the button into the
target pressure window and calls the “Go to Pressure” function.
VENT: Opens both positive and negative pressure ports to each other and atmosphere.
TARE: Zeros out internal pressure standard and re-zero’s mechanical components in
controller.
GO TO PRESSURE: Calls controller to generate pressure point set in pressure target box.
HOLD: Stops any process in action.
MONITOR: Switches calibrator into monitoring mode. This allows calibrator to be used
as pressure measurement device.
CONTROL: Switches calibrator into control mode. This allows the calibrator to be used for
pressure control and as a measurement device.
Error Graph is an auto-scaling display of the present error of the UUT’s output as com-
pared to the applied pressure. The red bars on the graph represent the UUT’s accuracy
specification limits. The labels will display the present range of the graph. The arrow
showing the error will turn red when the error is outside of tolerance.
