TRACK-100 is an ultra wide-range, battery operated, portable instrument for measuring Surface Resistivity of virtually any flat surface conforming to ASTM D-257 standard by using recommended parallel bar sensing probe.
In the circuit industry, products such as packaging materials, ESD shielding bags, work bench surfaces, static dissipative table and floor mats, conveyor belts, etc, have resistance values which need to confom to stringent specifications. Moreover, these values are expected to fall with in specified limits.  The Surface Resistivity Meter can play a vital role in monitoring and checking the resistivity characteristic of the above items.   
It also has unique additional feature of surface-to-ground measurement capability wherein the resistivity differential between any surface and any chosen ground can be determined. The surface resistivity is conveniently indicated by a row of LEDs covering a total of 10 decades from 103 to 1012 ohms per square.

Operation:                                                                                                                                                                                             1.Insert the banana plug on the end of the static strap ground cord into the jack located on the front of the wrist strap tester.    
2.The wearer of the anti-static wrist strap then pushes the metal pushbutton on the wrist strap tester.       
3..A properly operating wrist strap will give an "OK" LED indication on the anti-static wrist strap tester.  
If either RED "FAIL LOW" or YELLOW "FAIL HIGH" LED's light, and the audible indicator sounds, then the wrist strap should be discarded and replaced with a new one.
