Digital Pots Menu
Digital pots are electronically controlled digital potentiometers used for adjustments to operations of
the instrument. Each of the digital pots can go from 0-255. This menu should be accessed only during
diagnostics.
Unless the Control Loop is Disabled (refer to Section 3.4.13), changes to the pots may be modified by
the instrument. This is intentional; some diagnostics are best done with instrument feedback and
some are best done without.
