Switching From One Readout To Another - Velleman PersonalScope HPS5 Manual

Switching from one readout to another

The Personal Scope offers many voltage measuring possibilities.
Press the "readout" key repeatedly to select one of four possible
readouts :
Peak voltage (Vp).
True RMS readout (Vr). The area of the AC wave is calculated and
converted to voltage. Please remember that a correct readout invariably
consists of at least one or two visible periods (one can also use the auto-
setup
dB measurement (dB). The measured signal is converted to dBm
(0dB=0.775V). Once more, the user should make sure that at least one
or two periods are displayed or select the auto-setup function).
DC voltage measurement (V=). This function enables the user to
measure DC voltages (only for DC input coupling)
F
Useful tip for measuring DC voltages:
The readout can be set at zero (reference) for any position on the
screen by keeping the AC/DC key pressed down. Always use the
"run" trigger mode for DC voltage measurement.

We advise the user to use a measuring probe equipped with a X10
setting when high or unknown voltages or high impedances need to be
measured.
