Potentiometers
Pots from 200 Ohm up to 5 MOhm
The instrument provides two ranges for potentiometer mea-
surement. In Pot<5K measurement range, the measure is
direct (no additional configuration is needed). In Pot<5M it
is needed to introduce the nominal value of the potentiom-
eter to reach the assigned accuracy. This value is requested
when the Pot<5M is selected.
