You can configure the Tracker 300 series via the RS485 interface or by using a special PC to Tracker 300 cable, which plugs into the front panel "Config" socket. There are no internal links or potentiometers, so there is never any reason to open the unit. Each unit can be identified by a unique six character alpha numeric tag name, which is then stored in the instrument's memory.

The Windows based PC software allows you to name and store full configuration and calibration setup files for future use. You are able to print the Tracker 300 configuration that is supplied with each unit prior to installation. You can also test the Tracker 300 with our free SCADA software; download it now. If you wish to know more about PID, then you can view our article on how a PID controller works.
