Calibrating the meter involves:
Comparing the dispensers stated amount dispensed to actual
amount dispensed.
Adjusting the K-Factor if accuracy is not within the required
tolerance.
The K-Factor for each new dispenser is factory set
and usually does not need to be changed.
Record the dispensers current density factor and set it to read out in kg
Density Factor (dSF) (see page 27)
1. Test the meter accuracy using Calibration Test Fill Procedure -
Method 1 (see page 68) or Calibration Test Fill Procedure - Method
2 (see page 68)
1. Make sure that the dispenser is idle, with the nozzle in its holster.
2. Press and release the K-Factor switch nine times.
The display shows the K-Factor as F X.XXXX (single nozzle
dispenser) or FA X.XXXX (Side A of a dual nozzle dispenser).
To view the K-Factor for side B, quickly press and release the K-
Factor switch eight more times when viewing side A. The display
shows Fb X.XXXX (side B of a dual nozzle dispenser).
With a dual dispenser, it’s easier to set side A first.
3. Calculate the new K-Factor with the following formula:
New K-Factor = Existing K-Factor x True quantity
Displayed amount
For example:
Existing K-Factor = 0.98
Displayed amount = 5.80 kg
True quantity = 6.00 kg
New K-Factor = 0.98 x 6.00
5.80
= 1.0138 (4 decimal places)
1. Input the new meter K-factor (FA & Fb) (see page 27)
Set the density factor back to its original value. (dSF) (see page 27)
