AC VOLTAGE MEASUREMENT (RMS)
AC RMS Mode is for measuring AC (al-
ternating current ) voltages and can be used
on any AC voltage or pulsed waveform signal
where an RMS average voltage measure-
ment is required.
Contact the probe tip to the circuit and it will
display an RMS averaged AC voltage reading
in the main display area while also displaying
RMS Min/Max AC voltages on the top and
bottom left of the display.
Powering up and activating circuits with the
rocker switch can not be performed in this
mode.
Pressing the “CLEAR” button will reset Min/
Max readings.
AC RMS Voltage is used in the same manner as a standard DVOM
would be used to measure the averaged AC voltage in any circuit that
produces AC voltage. This can be used for, but not limited to, tests such
as checking alternator diode ripple, abs sensors, crank sensors, etc.
WARNING:
Do not use the
Maestro
™
to test AC line voltage such as 120V
wall plug. This will damage the probe and could cause personal injury.
Vehicle use only.
