Rotary switch
The measurement functions for each rotary switch position are described in
Table 1-5
(U1271A) and
Table 1-6
(U1272A). Turning the rotary switch changes
the measurement function and resets all other measurement options.
The U1272A model offers four additional rotary switch functions:
– Z
(low input impedance) voltage measurements,
LOW
– Smart Ω (offset compensation) measurements,
– Auto-diode test, and
– AC+DC voltage and current measurements.
The U1271A has one differing rotary switch function:
– Qik-V test.
Click the respective "Learn more" pages for more information on each function.
Some rotary switch positions have a shifted function printed in orange. Press
NOTE
to switch between the shifted and regular function. See
page 44
for more
information on the
key.
Remove the test leads from the measuring source or target before changing
WARNING
the rotary switch position.
