CALIBRATION OF LOAD CELLS
The ATX-2 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-2 will not operate
correctly.
1. Remove the rear panel.
2. Place end of 8 ft black hose (left side of ATX-2) in bulk used fluid container. Open ball valve on
the end of the 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.
a) 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.
b) 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.
