F02 Sim.Mode

Definition

Enables or disables the flow meter’s simulation mode. In simulation mode, the meter displays user-defined virtual flow values instead of actual sensor measurements. Default: Off.

Notes

1. After enabling this function, set the simulated flow in F01.

2. OCT (excluding pulses), RS485, and analog current outputs will operate based on simulated data and totalized flow, affecting both totalized values and historical records.

Operation Procedure

Button Functions (Click to Expand)

The main unit has four buttons. The bottom line (Line 3) of the LCD displays the current function of each button. Under normal operation, the button functions are as follows:

• Blue Button: Leftmost button: Return, exit, or save settings.

• Gray Direction Buttons:

  • Left Gray: Previous Page, decrease value, or select item

  • Right Gray: Next Page, increase value, or select item

• Orange Button: Rightmost button: Enter settings, edit, or confirm selection

Do not hold buttons for extended periods to avoid damage.

Button functions may change depending on the operation context to improve usability or prevent accidental presses

Simulation Mode Instructions (Click to Expand)

Simulation Mode is used to output simulated flow values for testing communication and signals. Related parameters include F01 Sim. Volume and F02 Sim. Mode, and additional settings depending on communication type:

• 4–20 mA: E06 Iout Def.

• NPN Pulse: E01 NO/NC, E02 OCT Info

• RS485: E04 Modbus ID, E05 Baud Rate
