Chapter 3, Operating Overview
Using USER Keys
Using USER Keys
User keys instantly access instrument settings without using the knob. You can
use user keys to move quickly between fields on the same screen, and to access
field settings that are not normally available on the screen you are using.
Local user keys are used to move between settings on the screen that is displayed.
When the user key is pressed, the cursor instantly moves to, and selects, the
assigned field; eliminating the need to turn and push the knob. Five local user
keys are available for each screen: k1, k2, k3, k4, and k5.
Five factory-assigned local user keys are available in each screen; however, using
these keys removes any other local user keys you may have already set up.
Global user keys are used to access settings that are not available on the current
screen. Three global user keys are available: k1’, k2’, and k3’. (These are shifted
functions of the local user keys.)
When defining user keys, the ASSIGN function is used to create key definitions;
the RELEASE function removes the definitions. Re-assigning a user key to a
different field setting automatically releases it from the setting it was previously
associated with.
