Chapter 3 Basic Measurements
3.1 Preparation
One of the first things you would like to do with your multimeter is to become acquainted with its front
panel. We have provided some exercises in foregoing chapters about preparations for use and
operations of front panel.
The front panel has six rows of keys to select various functions and operations. Most keys have a shifted
function printed in blue above the key. To perform a shifted function, press
Shift
(the
Shift
annunciator
will turn on). Then, press the key that has the desired label above it. For example, to select the AC
current function, press
Shift
then press
ACV
(ACI).
If you accidentally press
Shift
, just press it again to turn off the
Shift
annunciator.
