NOTE
・Calculation is carried out in the order No.1 through No.4.
・Also for channels where no input unit is installed, parameter calculation is
carried out if waveform processing results or data loaded from media are
stored in the channel.
・The scaling setting has effect. (RMS value and area value are calculated
after scaling.)
・When "
wave calculation
" is set to ON, waveform data after waveform
processing are used for parameter calculation.
Parameter calculation while capturing the waveform
･
Press the
START
key and LED light.
･
When the pre-trigger is set, the trigger will not be registered for a
certain period after the start of measurement. (During this interval,
Pre-trigger standby is shown on the display.)
･
When the trigger can be registered, the indication Waiting for
trigger is shown on the display.
･
Data recording starts when trigger condition are met.
･
When trigger mode selected AUTO, unit waits for about 1 second
for trigger conditions to be met. After this interval, data recording
starts, regardless of trigger state.
･
Displays "Storing". Waveform displays after data corresponding to
recording length have been stored in memory.
･
When the
STOP
key is pressed twice during measurement, the 8841
is forcibly stopped. (Parameter calculation are not executed.)
Displays "Calculating".
Displays parameter calculation result on the screen.
Depending on the results of the waveform parameter calculation, a GO
(pass) or NG (fail) result is returned.
When the evaluation result is GO:
･
Outputs GO signal.
When the evaluation result is NG:
･
Outputs NG signal.
･
The calculation value for that channel is marked with an "
*
" (on the
display and the printout).
･
Measurement is repeated until the stop conditions are met.

End of measurement.
Each time when trigger conditions are met, data are recorded and
memory contents are overwritten.
End of measurement in REPEAT and AUTO trigger modes
When the
STOP
key is pressed once during measurement, the 8841/42
acquires measurement data in an amount corresponding to the set
recording length, and the measurement is stopped. (Waveform
display, Parameter calculation are executed.)
When waveform parameter evaluation and waveform evaluation are carried
out simultaneously, measurement stops when either of the stop conditions is
met.
