Scale Factor Screen

3. Press

to advance to the next number in the scale

factor.

4. Repeat steps 2 and 3 for all five digits in the scale factor.

Note: All digits can be scrolled between 0 and 9 except
the first, which can only be scrolled from 0 to 1.

5. When finished setting the scale factor, press the

button and the scale factor and units measurement
screen will be replaced with the pulse delay screen:

Setting the Pulse Delay Factor

The

Pulse Delay Factor

is used to correct for fast flow

rates by closing the valve in the meter between one and
five pulses sooner than the selected value. The meter is
factory programmed with a pulse delay factor of 0.

Pulse Delay Screen

Advance through all five scale factor digits by pressing the

button. The above screen will now be displayed.

1. The 'PS-' will be followed by a flashing zero. The zero is
the initial setting of the pulse delay factor

2. Scroll between settings (0 to 5) by pressing the

button.

3. When finished selecting the pulse delay factor, press

and the display will return to the scale factor screen.

4. When finished programming these options, press the

<PROGRAMMING>

key and hold it until the screen

flashes three times then goes blank. Press the

button to return to the normal operating screen.

Recalibrating the Meter

The Scale factor is used to adjust the accuracy of the
meter. The scale factor will be set at the factory for oil. The
primary use for the recalibration function is if the user
wants to batch fluids with a viscosity other than 10W oil.
If the fluid has a lower viscosity, more fluid can slip past
the gears without being detected. Changing the scale
factor can adjust the meter to compensate for that loss
The meter multiplies each pulse by this number to correct
the accuracy when it converts to the specified units, so the
reading on the dial is always correct.

For an approximate scale factor for fluids of different
viscosities, consult the following chart:

(Unless otherwise specified at the time of the order, each
meter is programmed in quarts for use with motor oil.)

Note: The original meter scale factor is written inside of
the meter when calibrated at the factory. It may have been
revised after field installation. Use scale factor shown on
display, not the trigger.

To view the current program scale factor, do the following:

1. Press and hold the

button.

2. Then, press and hold the

button.

For an absolute scale factor, perform the following test:

Run a pre-measured batch of fluid through the meter. If the
meter is programmed to batch 4.200 quarts, and it batches
the entire amount but only reads 4.000 quarts, then the scale
factor needs to be adjusted. Divide the quantity delivers (4.2)
by the quantity dispensed (4.0) to get the error factor (1.05)

To calculate the new scale factor:

If existing scale factor is 1.0123, the calculation would be:
1.0123 (existing scale factor) x 1.05 (error factor) = 1.0629
(new scale factor)

Change the scale factor:

Press

<PROGRAMMING>

key to enter the programming

mode, and the

button to advance through the units

mode.

1. The first digit of the scale factor will be flashing.

2. Press the

button to scale through the numbers.
