Z05 Scale Factor

Definition

This function calibrates the flow meter’s accuracy. If the displayed flow differs systematically from a reference value, the user can set a scale factor to automatically correct the output.

Usage:

• The measured flow is multiplied by a fixed factor KKK.

• Range: +0.001 to +1000, default +1.0.

• Execution automatically updates K03 (Scale Factor).

Example:

Final Flow=Measured Flow×K\text{Final Flow} = \text{Measured Flow} \times KFinal Flow=Measured Flow×K

If actual flow = 101.5 L but meter shows 100 L, set K=1.015K = 1.015K=1.015.

Z-series parameters currently do not support Modbus read/write.

Notes

1. Z05 cannot accept negative values.

2. To measure reverse flow, enable A17 (Reverse Flow).

3. K03 serves the same function as Z05; users may choose either.

4. (Z-series parameters are for quick setup, consolidating multiple essential settings to simplify installation.)
