2 THE BUTTONS
The buttons respond differently to short, long, and sustained presses.
The , and keys provide additional functions as well as the
detection and acquisition of parameters complementary to the basic
measurements.
• Each of these buttons can be used independently of the others or in
conjunction with each other. This makes navigation simple and intuitive
when reviewing measurement results.
• It is possible, for example, to either look up in sequence the MAX, MIN,
etc. values of the RMS voltage alone, or look up in sequence all of the
MAX (or MIN, or PEAK) values of all power measurements (W, VA, var,
etc.).
In this section, the icon represents the possible positions of the switch for the
button’s functionality.
2.1
BUTTON
This button is used to:
 Store and look up the last values acquired specific to each function (V, A,
Ω, W) according to the specific modes previously activated (MAX/MIN).
The present display is then maintained while the detection and acquisition
of new values continues.
 Perform automatic lead resistance compensation (see § 3.6.1).
 Perform automatic zero correction in
