8. If calibrating the machine with the “Auto Cal”, the machine will
automatically run thru a number of steps and calibrate the
machine on its own. This calibration can take anywhere from
30-60 seconds and when it is finished it will ask for the user to
select “Accept” or “Cancel”. Select the “Accept” button to finish
the calibration process or “Cancel” to abort and run it again.
9. When unplugging the EZ-CAL USB load cell from the polishing
machine, first transition to the HOME tab so the load cell is not
taking readings. When the machine is on the HOME tab the load
cell readings are halted making it safe to unplug the device.
When using an external master load cell follow these steps to
calibrate the machine.
1. Remove the polishing fixture from the Overarm and the rubber
pad from the top of the Platen.
2. Clean the top of the Platen to remove any water, grit, or dirt from
the surface to ensure that the external master load cell will be set
on a clean, dry surface.
3. Place the external master load cell on
the Platen and center it under the
Overarm plunger.
4. Allow external master load cell to
warm up 15 minutes prior starting
calibration.
5. On the touchscreen, select the “System Config” tab, then select
“Load Cell Calibration” in the configuration drop down box using
the DOWN arrow as necessary (Fig. 3).
6. Select the “Manual Cal” button to begin the calibration process.
7. Once step one of the manual calibration process starts, raise the
Overarm just enough for the plunger to clear the master load cell
and select the “Tare” button on the touchscreen checking to see if
the master load cell reads 0 lbs. while doing this.
8. Once step two activates, lower the
Overarm back down onto the
master load cell and lock it into
place by releasing the illuminated
arm button. When ready select the
“Apply Pressure” button on the touchscreen. Press the “Increase”
and “Decrease” buttons on the screen until the master load
cell reading matches the 24 lbs. of polishing machine load cell.
