K02 Calibration Mode

Options
RS-485 Numbers
Remarks

Simple mode

0

Default

The simple calibration mode applies a formula to adjust the instantaneous flow rate:

Calibrated instantaneous flow = (K03 × uncalibrated instantaneous flow) − K04

Example 1 If the desired calibrated flow rate is half of the current displayed value, set K03 to 0.5, and leave K04 at the default value 0.

  • Example:

    • Uncalibrated instantaneous flow: 5.0 L/min

    • Calibrated instantaneous flow: 2.5 L/min = 0.5 × 5.0 L/min

Example 2 For multi-point calibration requiring the addition or subtraction of a constant to maintain linearity:

Uncalibrated Flow Rate
Target Calibrated Flow Rate

10

4

20

9

Set K03 to 0.5 and K04 to 1.0.

  • 4 L/min = 0.5 × 10 L/min − 1.0

  • 9 L/min = 0.5 × 20 L/min − 1.0

K03 Scale Factor

A proportional adjustment to the flow rate, default is 1.0. This parameter is synchronised with Z05.

Maximum

1000.

K04 Manual Offset

A fixed value is subtracted from the instantaneous flow rate according to the input. The unit matches the system setting.

  • Example: Entering 1.0 subtracts 1.0 from the current flow. If the original flow is 3.0, the output becomes 2.0. Default value: 0.0. This parameter functions similarly to Zero Offset but operates independently.

K05 Totalizer Scale (Cumulative Total Ratio)

Adjusts the ratio of the amount added to the Totalizer from the calibrated instantaneous flow. It does not affect previously accumulated data. Adjustments amplify both positive and negative values.

  • Use case: Maintain the same instantaneous flow data while accounting for differences in cumulative values (e.g., using density to reflect weight).

Default value: 1.0.

Data Type

Default

1

Minimum

Maximum

1000

Formula:

New cumulative value = Previous cumulative value + (K05 × newly added calibrated flow)

Example: If the Totalizer currently increases by 1 L/min, and the cumulative value is 100 L, to double the accumulation rate without altering the flow rate, set K05 to 2.0:

  • New cumulative value = 100 + 2 × 1 = 102 L
