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 recalibration is to batch fluids with different viscosities. If the fluid has a different

viscosity, the scale factor must be changed to accurately measure it. The meter multiplies each pulse by the scale factor to

correct the accuracy when it converts to the specified units. For an approximate scale factor for fluids of different viscosities,

see "Chart of Approximate Scale Factors" on page10.

OTE:NThe meter’s original scale factor was written on the trigger when it was calibrated at the factory. It may have been

revised after field installation. Use the scale factor shown on the display, not on the trigger.

To view the current scale factor, press and hold TOTAL and then AUTO.

Dimensions

Absolute Scale Factor

For absolute scale factor, perform this test:

1. Run a batch through the meter.

2. If the meter measures a dierent amount than the batch amount, the scale factor needs to be adjusted. For example, if you

run a 4.20 quarts batch and the display shows only 4.00 quarts, the scale factor needs adjustment.

3. Divide the amount of liquid in the batch (4.20) by what the display shows (4.00). The result is the error factor (1.05).

4. Find the current scale factor by pressing and holding TOTAL and then AUTO. For this example the current scale factor is

1.0123.

5. Multiply the current scale factor by the error factor to nd the new scale factor (1.0123 × 1.05 = 1.0629).

6. Enter the new scale factor as described in the "Change Scale Factor" on page9.

OTE:NUse the current scale factor shown on the display, not on the trigger.
