Understanding the Rotary Switch

Select a primary measurement function by positioning the rotary
switch to one of the icons around its perimeter. For each
function, the Meter presents a standard display for that function
(range, measurement units, and modifiers). Button choices made
in one function do not carry over into another function. The
model 289 offers two additional functions: low ohms (Y) and
low impedance (LoZ) ac volts. Each position shown in Figure 3 is
described in Table 4.
