Calculate scale factor
A scale factor is a number used to adjust
meter accuracy. The scale factor is set at the
factory using motor oil with a viscosity of
10W.
The primary use for scale factor recalibra-
tion is to batch fluids with different viscosi-
ties. If the fluid has a lower viscosity, more
fluid can slip past the meter gears without
being detected. Changing the scale factor
adjusts the meter to compensate for the
loss.
To view the current scale factor
Press and hold the total button and the
auto button at the same time.
For an approximate scale factor for differ-
ent viscosities, refer to diagram.

Notice
Original scale factor of meter was
written on trigger when calibrated at
factory and may have been revised after
field installation. Use scale factor show-
ing on display, not on trigger.
Changing scale factor will change
accuracy of meter, potentially causing it
to overfill or under fill, causing a poten-
tial mechanical breakdown.
Absolute scale factor test
For absolute scale factor, perform this test:
1 Run a measured amount of fluid through
the meter.
2 If the meter delivers 4.20 qt. (3,9 l) and
the display shows only 4.00 qt. (3,7 l)
then the scale factor needs to be adjusted.
3 Divide what the meter delivered 4.20 qt.
(3,9 l) by what the display shows 4.00 qt.
(3,7 l). You get an error factor of 1.05.
4 The existing scale factor is 1.0123, as
shown in steps 1 and 2 in To view the
current scale factor, this page.
5 To calculate a new factor: 1.0123 (exist-
ing Scale Factor) x 1.05 (error factor) =
1.0629 (new scale factor). Enter that
number as described in the change scale
factor section of this manual.
6 Enter that number as described in change
scale factor.
