Preliminary Testing and Calibration:
The system will weigh accurately only in the first stage on a truck that has multiple telescoping lift cylinders.
A weighing height must be established and the best method to reach the weighing height must be determined. Setting zero, as well
as weighing a load, must all be done in the same manner. Repeatability is the key to accurate weighments. We will use a method of
lifting then lowering a few inches to the set height, but if lifting to the height without lowering gives better results, then do it that
way.
You will need to have a known weight available that is evenly distributed The weight should be at least 40% of the lifts capacity,
but if it is not available, a lesser weight can be used.
1. Assure that the mast is not tilted, then raise the forks to aprox. 16 inches above ground level.
NOTE:
On loaders, the height should be at the height that would be used to load into a truck.
2. Use a piece of tape to make a mark on the mast and the carriage so the lift height can be seen and repeated easily by the lift
operator.
3. Lower the lift back to the ground, then lift to aprox. 2 inches over the tape marks, then jog the lift down to the marks.
4. Press and hold the PRINT button in while turning the power on.
5. When the display shows ------ release the PRINT button.
6. Press and release the TOTAL button.
7. Press the ZERO button until the display shows zero.
8. Lower the lift and get the test load on the forks.
9. Lift the load to aprox. 2 inches over the tape marks, then jog the lift down to the marks.
10. Allow the pressure to settle for aprox. 5 seconds.
11. The weight display can be altered up or down by pressing and holding the TOTAL button to make the display go down, and
holding the PRINT/+ button to make the display go up.
12. Use the PRINT and TOTAL buttons to make the display come as close to the test weight as possible without spending a lot of
time. The weight display may be changing by itself due to hydraulic bleeding.
13. Turn the power OFF and then turn it back on.
14. The system is ready for repeatability testing. tinue to press the LOCK/NORMAL until the dashes stay on the display for a longer period of
"T" fitting (not included)
Full feature digital scale system for lowest cost. Made in U.S.A. at our San
Diego plant.
Complete system for any hydraulic lifting equipment. The unit has
adjustable parameters for automatic weight capture and capture and add for
front-end-loaders. Display
modes for display of Current Load or Total Weight. Printer data output for
recording each load and total.
