NOTE
INPUT A in Meter mode can make separate V DC and
Vrms AC measurements on the same signal at the same
time. V DC and Vrms AC readings are normally displayed
together.
V DC METER Measure the DC (direct) voltage of the
input signal in Meter mode.
Vrms AC METER Measure the RMS (Root Mean
Square) voltage of the input signal in Meter mode. This is
done with DC- coupled input. Allows AC component of
signal to be displayed
Vrms AC+DC METER Measure the true RMS (Root
Mean Square) voltage of the input signal in Meter mode. If
a DC-offset is present, this measurement will read higher
or lower than Vrms AC. If there is no DC offset present, this
measurement will be the same as Vrms AC.
V DC (mean) SCOPE Measure the mean (average of
readings) value of the waveform between the (vertical)
cursors in Scope mode.
Vrms SCOPE Measure the RMS (Root Mean Square)
voltage of the waveform between the (vertical) cursors in
Scope mode.
dV SCOPE Measure the voltage difference between
the (horizontal) cursors in Scope mode.

V peak/peak SCOPE Measure the difference between
highest and lowest voltage value of the waveform between
the (vertical) cursors in Scope mode.
Vmax peak SCOPE Measure the maximum peak value
of the waveform between the cursors in Scope mode.
Vmin peak SCOPE Measure the minimum peak value
of the waveform between the cursors in Scope mode.
dBV DC METER (decibel Volts) Measure the voltage
ratio of the DC component of a signal with respect to a
reference voltage in Meter mode. This is done with DC-
coupled input.
dBV AC METER (decibel Volts) Measure the voltage
ratio of the AC component of a signal with respect to a
reference voltage in Meter mode. This is done with DC-
coupled input.
For dBV, you can select a range of references by pressing
or . Choose a voltage between 50 mV and
9.99V. The default value is 1V.
