3.2 Voltage measurements (V)
1. Connect the measurement leads to the instrument’s
terminals, complying with the polarities indicated: red lead
on the “+” terminal and black lead on the “COM” terminal.
2. Set the rotary switch to position "V ".
3. Connect the assembly to the voltage source to be
measured, making sure if possible that this voltage does
not exceed the maximum acceptable limits (see table
below).
Range switching and AC/DC selection are automatic.
Actuate the yellow key to force AC/DC selection manually
if necessary.
If the signal measured is > 45 V peak, the audio indication
is activated if the V-Live function is selected
(see § 3.12.9).

(1) In DC, the display indicates +OL
above +600 V and -OL
above -600 V (900 V in PEAK mode).
In AC, the display indicates OL over 600 Vrms (900 V in
PEAK mode).
(2) In AC if the value of the voltage measured is < 0.15 V the
display indicates 0.00.
