Keithley DMM6500

Why did my settings change?
Many of the commands in the DMM6500 are saved with
the measure function that was active when you set them.
For example, assume you have the measure function set
to current and you set a value for display digits. When you
change the measure function to voltage, the display digits
value changes to the value that was last set for the voltage
measure function. When you return to the current measure
function, the display digits value returns to the value you set
previously.
