7-14 Performing the Measurement Model 831 Manual
The OK response will already be highlighted, so simply
press the
5
(ENTER) key to continue.
Otherwise, highlight Cancel and then the
5
to cancel both
the Stop and the Reset operations.
After selecting to Stop the measurement, the Save File
Menu, shown in FIGURE 7-13, will appear to provide a
choice of saving the measured data prior to the reset or not
as described in “Storing the Measurement” on page 7-15.
Resetting When Stopped
If the Model 831 is stopped when the
1
key is pressed, the
Stop Required Menu will not appear, but the Save File Menu
will appear to provide a choice of saving the measured data
prior to the reset or not.
After the reset has been performed, the
7
key will
produce a steady red light to indicate the measurement state
as Stopped, Reset.
Starting a New Measurement
The
9
key (RUN/PAUSE) key must be pressed to start a
new measurement.
Stopping the Measurement
Note that the Model 831 can be
stopped when either running or
paused. Press the
7
key to suspend the overall measurement,
which will also stop the run clock. Stopping the
measurement with data not yet stored will cause the
7
key
to flash red every 3.2 seconds.
Pressing the
9
key afterwards will continue the overall
measurement which had been stopped. The run clock will
also begin again from the time indicated when the stop had
occurred. This will also cause the
9
to produce a steady
green light.
