2-2-6 MEASURE
MEASURE
Push the MEASURE button to access
the automated measurement capabilities.
It has the ability to display up to five
parameters at a time. When this menu is
selected, submenu NONE, Pk-Pk, RMS,
Mean, Frequency, Rising Time, Falling
Time, Period, +Width, -Width and Duty are
displayed.
Pk-Pk : This displays a Peak to Peak value of the waveforms of the currently
displayed channels. That is, absolute gap between maximum and minimum
amplitude is displayed with volt. When input signal is out of the ADC input
range , "?" is displayed.
Maximum value and minimum value are equal, "Invalid" is displayed.
RMS : This displays a Root Mean Square value of 1 cycle of the waveforms
of currently displayed channels. When range of input signal is out of the
ADC input range, peak to peak value is less than 2 division, or width of
1 cycle is less than 0.4 division on display, "?" is displayed. When 1 cycle is
not captured, "Invalid" is displayed.
Mean : This displays a mean value of 1cycle of currently displayed
waveforms. When range of input signal is out of the ADC input range,
peak to peak value is less than 2 division, or width of cycle is less than
0.4 division on display, "?" is displayed. When 1 cycle is not captured, "Invalid"
is displayed.
Frequency : This displays a frequency value of 1 cycle of currently
displayed waveforms. When range of input signal is out of the ADC input
range, peak to peak value is less than 2 division, or width of 1 cycle is less
than 0.4 division on display, "?" is displayed. When 1 cycle is not captured,
"Invalid" is displayed.
NONE : This cancels the measuring
functions of parameter.
