THEORY OF OPERATION

The Test Platform moves at a constant speed causing friction between itself and the
stationary Test Sled. An electronic load cell measures the force, then feeds the
information to a data acquisition unit. The data acquisition unit collects the data from
the load cell and stores these data points in memory for use in calculating the
maximum, minimum and average values. The forces generated during the test are also
used in calculating the Static COF and Kinetic COF of the test material.

POWER UP

Turn on the master power switch located on the back panel of the control cabinet next
to the power line receptacle.
WARNING: Operating temperature for this equipment is 32 to 150
degrees Fahrenheit (0 to 70 degrees Celsius). The equipment needs to be
completely free of condensation, inside and out, before applying power.

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 COF-1000. This procedure should
be followed upon first use of the COF-1000 and whenever necessary thereafter. The
following is the step-by-step procedure for calibrating the load cell.
Make sure that the COF-1000 has been powered on for 30 minutes before
proceeding with calibration.
