1. DC voltage measurement (V=).
This function enables the user to measure DC
voltages (only for DC input coupling)
2. Maximum voltage (Vmax.).
The signal's positive peak voltage (difference
between zero and highest value) is displayed.
3. Minimum voltage (Vmin.).
The signal's negative peak voltage (difference
between zero and lowes value) is displayed.
4. Peak to peak (Vpp).
The signal's peak-to-peak voltage (difference bet-
ween highest and lowest value) is displayed.
5. True RMS readout (Vrms ac)
The true RMS value of the AC wave is calculated
and converted to voltage.
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.
