CESM303-COF is a package for COF testing. All items that are needed to perform a COF test is included.

The speed of the COF test can be set in the ESM303 motorized test stand controller. This test stand has limit switches witch can be used to stop the cross-arm. Additional options can be added to the test stand if needed.

Static and kinetic coefficients are displayed on the backlit LCD of the M5-2-COF, and are calculated from a user-programmable sled weight.

	Included	ESM303 Motorized Test Stand Selectable speed setting. Password Protection of test parameters.
	Included	M5-2-COF COF Force Gauge Calculates static and kinetic coefficient of friction. Sled weight is inserted in gauge menu for calculation of COF.
	Included	G1086 Coefficient of Friction fixture COF table, sled and string.
	Included	09-1214 Cable Force Gauge to test stand communication cable
	Included	09-1158 Cable Force Gauge to test stand communication cable
	Optional	AF012 Overload Protection
	Optional	AF013 Auto Return
	Optional	15-1005 Data Acquisition Software

The ESM303 motorized test stand can be used for a lot of different tests. This package with accessories is for COF testing. Additional force gauges, grips, fixtures and optional functions can be added for running other tests.

The M5-2-COF has a 2 lbf capacity, because COF forces are very low forces. If other tests will be performed you will likely need a higher capacity force gauge for those tests.

Static and kinetic coefficients are displayed on the backlit LCD of the M5-2-COF, and are calculated from a user-programmable sled weight.

M5-2-COF Features

	The M5-2-COF performs COF calculations by dividing the force by the sled weight. For example, a force of 100 gF divided by 200 g equals 0.5 COF. Although many COF testing applications require a sled weight of 200 g, the gauge allows the user to change the sled weight to comply with other requirements. To modify the sled weight, select COF from the menu.
	Average mode is used to obtain an average force over time. This reading also represents the kinetic coefficient of friction for the M5-2-COF gauge. The minimum force required to start the averaging sequence. Initial delay follows the trigger force.
