Frequently asked questions
How do I clear the total cumulative flow value?
In normal display mode, press the “+” and “V” keys together to reset the total cumulative value.
What alarm output options are available?
The instrument provides up to three isolated 24 VDC/30 mA output channels that can be assigned to upper‑limit, lower‑limit or quantitative alarms.
How can I enter the parameter setting mode?
Long‑press the SET key for 3 seconds to enter the parameter setting state; use PLoc codes (e.g., 1008 for primary parameters) to select the level.
Which input signals can be compensated for temperature and pressure?
The device supports temperature compensation via thermocouples, RTDs and voltage inputs, and pressure compensation via 0‑5 V, 0‑10 mA, 4‑20 mA or 0‑20 mA signals.
