Operating Sequence for Series 9800 Only
The Atlas Fuel System
For example: Assume that the adjuster setting at the start of the test reads 2.05. The product is
run through the meter into a Prover Can until the counter registers 100 gallons.
Assume that the Prover Can shows a volume of 98.7 gallons (1.3 gallons short).
Since the adjuster graduations are in percent readings, this 1.3 could be added
directly to the adjuster reading (2.05 plus 1.3 equals 3.35 on the adjuster). A
rerun through the meter must then show 100 gallons both on the meter counter
and on the Prover Can.
If you are measuring in increments of less than 100 gallons, use this simple
formula to determine the percentage by which the adjuster must be adjusted:
(
P
-
M
)/
M
=
A%
where
P
is the prover measurement,
M
is the meter reading, and
A%
is the
percent adjustment for the adjuster.
Calibration Adjustment for E85 and DEF Units [Electronic Calibration
(ECAL)]
E85 and DEF units must be calibrated electronically. To perform the Electronic Calibration
(ECAL), proceed as follows:
Notes: 1) If the unit is two-sided, then the calibration procedure must be performed
individually on each side.
2) The calibration switch is located on the junction box side of all three E85 unit types

Slide the back cover and turn the Calibration switch to “Calibrate” position (up).
a
Locate the calibration assembly, slide the W & M seal metal cover towards the exterior of the
unit.
b
Locate the inside switch for side B, or the outside switch for side A. Place the switch in the up
position to activate the calibration procedure.
