In this installment, we show how to enter options codes on both the USM and DMS sides of the Go instrument. There are many options available for the Go series for various special evaluation modes and data recorder features. These may be purchased at any time and entered in the field with no need to send the instrument to our service centers for upgrade. Options are enabled by entering special six digit codes that are generated uniquely for each serial number of instrument. In this video, we show the proper way to enter those codes and some of the common errors that occur.
