Testing and Measuring Operations
AC Voltage Measurement (P to P)
P-P
mode can be used on any AC voltage signal where
a Peak to Peak (P-P) voltage measurement is required.
P-P stands for Peak to Peak AC voltage. Where AC RMS
displays an averaged AC voltage, P-P does not average
the reading but displays the total voltage difference from
the lowest to highest voltage extreme on an AC signal.
In this mode, the display will be an AC Voltmeter that shows
the Tip Voltage in the center and the Min/Max voltage
readings along the bottom of the display.
The voltage displayed is the total voltage potential between
the lowest and highest voltage sensed on the AC signal be-
ing measured.
Powering up and activating circuits with the rocker switch
can not
be performed in this mode.
The total Peak to Peak voltage will be shown in the main
display area. The Min voltage will display lowest absolute
voltage on the bottom left of the display and the Max volt-
age will display the highest absolute voltage on the bottom
right of the display.
For example, if you have an AC signal that alternates from -50V to +50V the Power Probe IV will
display a P-P voltage of 100V, a Min voltage of -50V and a Max voltage of +50V.
Pressing the “CLR” button will reset the Min/Max values.
This can be a more accurate test for signal circuits such as sensors or data communication lines
where measuring the full range of the AC signal is required.
The Power Probe IV can measure P-P AC voltage from -100V to +200V or a Maximum RMS AC
voltage of 70V.
