UNI-T UTD3025C

Automatic measurement of voltage parameters
Voltage parameters which can be measured b
y
UTD2000/3000 series osci llograph automaticall
y
are as follows
:
Peak value (Vpp): Voltage from the highest
waveform point to the lowest waveform point
;
The maximum value (Vmax): Voltage from the
highest waveform point to GND (ground)
;
The minimum value (Vmin): Voltage from the lowest
waveform point to GND (ground)
;
Middle value (Vmid): Half of sum of waveform top
and bottom voltage
;
A
mplitude (Vamp): Voltage from waveform top to
bottom
;
Middle value (Vmid): Half of sum of waveform top
and bottom voltage
;
Top value (Vtop): Voltage from flat wa
v
eform top t
o
GND (ground)
;
Bottom v alue (Vbase): Voltage from waveform
bottom to GND (ground);
Overshoot: Ratio of difference of the maximum
waveform value and top value and amplitude
;
Preshoot: Ratio of difference of the minimum
waveform value and bottom value and amplitude;
A
verage value: Average amplitude of s ignals withi
n
a cycle
;
Root-mean-square (Vrms): It is effective value
.
Root-mean-square refers to DC voltage of
converted energy within 1 cycle according to A
C
signal to correspond to equivalent energy
