Auxiliary Displays
The screen in Figure 6.4.1.5-A shows all of the possible auxiliary display items that can be included in the Home App. The
instrument can have up to three auxiliary displays which can be chosen by clicking on each button and then selecting the display
item from the menu on the right side of the screen (Figure 6.4.1.5-B)

Figure 6.4.1.5-B Auxiliary Display Selection
Some of the auxiliary display can be modified by pressing the displayed button. Others simply display auxiliary information.
■
Peak:
Pressing the Peak button will reset the upper and lower peak value to the current reading, subsequent negative or
positive divergence from that reading will be recorded in the button.
■
Rate:
Pressing the Rate button will display a choice of time rate units for the rate denominator.
■
Rate Setpoint:
Pressing the Rate Setpoint button will let the user enter the new Rate Setpoint via the numeric Keypad
(“Variable”) or select “Slow” (.1% of the span of the primary transducer), Medium (1% of the span of the primary transducer), or
“Fast” (10% of the span of the primary transducer).
■
Uncertainty:
Displays the accuracy at the pressure being displayed.
■
Units:
Pressing the Auxiliary Units button will display the same set of units available for the primary units. Pressing any of these
units will change the auxiliary units to that chosen unit.
■
Digital I/O:
Displays the current state of digital inputs and outputs as “1” for high and “0” for low.
■
Source Pressure:
Displays the current source pressure at the supply port.
6.4.1.6
Zero Button
If the Zero Calibration function has been chosen in the Display Settings App (Section 6.4.4), then the Zero Cal Button [
]
will appear in the Home App. If the instrument is measuring absolute pressure, and the Zero Cal Button is pressed, a keyboard will
appear to allow a single point calibration. If the instrument is measuring gauge pressure, pressing the button will set the current
reading to zero. If the instrument is in emulation mode (absolute or gauge) then the value will not be saved to the transducer but
only as a temporary adjustment while in emulation mode. After exiting the emulation mode or after a power cycle, the temporary
adjustment will be cleared. The zero adjustment for an instrument not in emulation mode will be saved to the transducer as if single
point calibration had been performed.
Figure 6.4.1.6 shows the zero cal function been enabled for instrument. The background color of the zero button will momentarily
change to a lighter color as the zero calibration is performed then will revert back to a darker color when complete. The screen on
the right shows this.
