2.1.1 Main Menu Functionality
There are three options on the Main Menu, CONFIG, {current display} and MORE. The
Main Menu is home for the menu display.
2.1.1.1 Setting the Current Display
The current display is indicated by the center option on the Main Menu, pressing the F2
key will toggle the current display.
2.1.1.2 Setting Current Display Parameters
To set the parameters of the current display use the CONFIG option to get to the Display
Configuration Menu.
Here the SELECT option will toggle through the choices for each parameter. The first
parameter is MODE. Since voltage, current and switch test modes all use the same
jacks, two of these functions cannot be used concurrently. The ability to select certain
functions is limited based on what is already selected in another active display. The
NEXT option is used to change to the second parameter. Only RTD and Pressure modes
have a second parameter, RTDs can be read in Celsius or Fahrenheit and Pressures can
be read in 3 engineering units.
With a single display the following modes are available:
P[] = Pressure on left side sensor.
P[2] = Pressure on right side sensor.
[EXT] = Pressure with external pressure module.
P[] ST = Switch Test with left side sensor.
P[2] ST = Switch Test with right side sensor.
[EXT] ST = Switch Test with external pressure module.
mA = Milliamps measure without loop power.
mA LOOP = Milliamps measure with loop power.
VOLTS = Voltage Measure.
RTD = RTD Temperature Measurement (if a probe is connected).
The following table shows which functions are available concurrently.
An X in a column indicates that the mode in the current display will not be available for
selection if the mode in that row is in use in any other active display.
