The DPM is equipped with Alarm and Diagnostics Events registers. These are
available via digital interface and an optional OLED screen indication. The
Alarm Event Register monitors non-critical alarm events related to the meter
settings and process variables. The Diagnostic Event Register monitors critical
diagnostic events related to meter performance and peripheral hardware
conditions.
NOTE : The AP Sensor Tare procedure requires high accuracy (at
least 0.2% of reading) absolute pressure sensor reference standard.
The AP sensor Tare result will be as accurate as your reference
absolute pressure sensor is.
