NOTE
Calculation is carried out in the order No.1 through No.16.
Also for channels where no input module is installed, numerical calculation
is carried out if data loaded from media are stored in the channel.
The scaling setting has effect. (RMS value and area value are calculated
after scaling.)
Numerical 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, instrument 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 8855
is forcibly stopped. (numerical calculation are not executed.)
Displays "Calculating".
Displays numerical calculation result on the screen.
Depending on the results of the numerical calculation, a GO (pass) or
NG (fail) result is returned.
When the evaluation result is GO:
Outputs GO signal.
Continue measurements, until NG result appeared.
When the evaluation result is NG:
Outputs NG signal.
When a NG occurs, the numerical values of the channel that
experiences the error are displayed red on the screen. NG channels
are represented by an "x" on the printout.
Result to printer ON Prints the evaluation results.
Result save ON Saves the evaluation results.
Auto print ON Prints the measurement data.
Auto save ON Saves the measurement data.
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 8855
acquires measurement data in an amount corresponding to the set
recording length, and the measurement is stopped. (Waveform
display, numerical calculation are executed.)
When numerical evaluation and waveform
evaluation are carried out simultaneously,
the waveform evaluation stop mode is given
priority.
