Stopping Measurement Collection
There are two methods of stopping the collection of measurements for the statistics
function.
To manually stop the measurement collection, press the
STOP
soft key from the
statistics menu. The display will update with the final set of statistical data.
The process can also be stopped automatically by entering the number of samples on
which you want to calculate statistics. To enter the number of statistic samples:
1.
While in the statistics function, press
#SAMPLES
.
To select the digit to adjust, press the soft key labeled either
<--
or
-->
.
With the desired digit selected, press the soft key labeled
--
to decrement the digit
or
++
to increment the character.
2. Press
ENTER
to set the number of samples.
Note
Setting the number of samples to zero will cause the Meter to collect
samples continuously.
Testing Using Limits
The limits function provides Pass/Fail testing to user specified upper and lower limits.
The upper and lower limits are stored in volatile memory and will be set to zero when the
Meter is first turned on or the meter receives a reset through the remote interface.
Changing the function will also set the limits to zero.

measurement.
For remote operation, the Meter can be set to generate a service request (SRQ) on the
