K05 Totalizer Scale

Definition

Adjusts the totalizer accumulation rate without changing instantaneous flow values. K05 scales the amount added to the totalizer each cycle, allowing the totalized value to be increased or decreased. Default: 1.0.

Operates according to the formula:

$$\text{New Totalizer Value} = \text{Previous Totalizer Value} + K_{05} \times \text{Volume Added This Interval}$$

Example:
Customer requirement: Display cumulative total as weight while keeping instantaneous flow in L/min. 
Liquid density: 1.20 kg/L.
Settings: (K05 = 1.20)
Calculation:
* Previous totalizer: 250.00 L
* Current instantaneous flow: 150 L/min → Volume in 1 second = 2.5 L
Formula:
New Totalizer＝Previous Totalizer + (K05 Current Volume)
Result:
New Totalizer 
= 250.00 + (1.20 x 2.5) 
= 250.00 + 3.00 
= 253.00 (kg)

Notes

1. This setting does not affect previously accumulated data.

2. Adjusting (K05) scales both forward and reverse flow proportionally.

3. K05 must be a positive value.

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 Arrow Buttons:

• Left Gray Button: Page up, increase value, or select item

• Right Gray Button: Page down, decrease 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.
