MACHINE SETUP

LOAD CELL CALIBRATION
It is important to calibrate the load cell to ensure that reliable data will be gathered. A
calibration procedure is built into the software of the Probe Tack Tester. This procedure
should be followed upon first use of the Probe Tack Tester and whenever necessary
thereafter. The following is the step-by-step procedure for calibrating the load cell.
Make sure that the Probe Tack Tester has been powered on for 30
minutes before proceeding with calibration.
The calibration sequence defaults to grams as the unit of measure. Make
sure that your calibration weights and entries are in grams.
LOAD CELL CALIBRATION PROCEDURE
1. Select SETUP from the main screen.
2. Select CALIBRATE LOAD CELL from the setup screen.
3. The first screen in the calibration process describes the 2 point calibration
process. Select OK to continue.
4. The next screen measures the low calibration value (typically 0). Make sure that
you do not have a weight hanging from the calibration wire and select OK.
5. The next screen measures the high calibration value. This weight should be
close to the maximum rated load cell value. Hang the weight on the loop end of
the calibration wire making sure that the wire is able to move freely.
6. Set the high calibration value by selecting CHANGE and entering the value of the
weight in grams and select ENTER.
7. Make sure that the calibration weight is completely at rest and then select OK.
