This menu selection provides information about current 2.5Vdc reference
voltage value as well as different parameters of the Temperature/Pressure
Compensation Algorithm, which may be useful for meter troubleshooting (read
only). A typical Reference Voltage and DSP Calculation diagnostic screen is
shown in Figure 48:

NOTE: Actual content of the Reference Voltage and DSP Diagnostic screen
may vary depending on the model, device configuration, and meter operational
state. Consult your factory customer support representative for more details
about Reference Voltage and DSP Calculation troubleshooting.
6.5 Multi-Functional Push-Button Operation
The DPM provides the user with a micro push-button switch accessible via a
small hole on the right side of the instrument (see Figure 49), which can be
used to select/start some important actions for the instrument. The micro
push-button switch functionality is available on all DPM models in both analog
and digital operation mode.
Pressing a switch briefly (< 6 sec) will not cause unwanted actions but will
provide the currently selected mode for this instrument's communication port.
The response will be with one of three signals, as indicated below:
1 AMBER flashing "Communication Port Disabled"
2 AMBER flashing "RS-232"
3 AMBER flashing "RS-485"
