Ranging
If your application is easier to perform using a manual range that you select, the YSI Model 3100
allows you to turn off the default autoranging feature. While you are making conductivity or
temperature compensated conductivity measurements, simply press and release the [ENTER]
key. The conductivity units will flash indicating that the instrument is now in a manual range.
Each additional press of the [ENTER] key will cycle the Model 3100 to a different manual range
until you return again to autoranging. Six pushes of the [ENTER] key will cycle the Model 3100
through the five available manual ranges and return the instrument to autoranging.
