CALIBRATION OF LOAD CELLS

The ATX-3 has two tanks, each mounted on a load cell. One tank is for new fluid and one is for used
fluid. Each tank is permanently bolted to a load cell platform which can not be removed from the unit.
The calibration procedure below must be performed for both load cells.

Never calibrate only one load cell as an imbalance may occur and the ATX-3 will not operate
correctly.

1. Remove the rear panel.

2. Place end of 8 ft black hose (left side of ATX-3) in bulk used fluid container. Place any adapter

onto coupler on end of hose.

3. Press and hold 4 QUARTS and 20 QUARTS buttons until a long beep is heard.

4. Select which load cell is to be calibrated.

Press -1/2 QUART to calibrate the used fluid load cell. REMOVE USED FLUID will be flashing
throughout the remaining steps. A short beep will be heard.

Press +1/2 QUART to calibrate the new fluid load cell. ADD NEW FLUID will be flashing
throughout the remaining steps. A short beep will be heard.

The pump will run and empty the contents of the selected tank through the 8 ft black hose into the
collection container.

5. Press the STOP button when fluid is no longer leaving the machine through the black hose and the

selected tank is empty. The pump will stop running. The 4 QUARTS will be flashing. A short beep
will be heard. Check that the tank is empty.

6. Press the STOP button again. The 12 QUARTS will be flashing. A short beep will be heard. This

programs the minimum weight.

7. Place two 5 kg or one 10 kg

calibration weight on the top of the
selected tank. (10 kg = 22 lbs)

8. Press the STOP button. The 12

QUARTS will be illuminated. A short
beep will be heard. This programs the
maximum weight.

9. Remove calibration weight(s) and

replace rear cover.

10. Press the STOP button again. A short

beep will be heard. The machine
returns to regular operating mode.
