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.

When testing from the front panel, the Meter displaysOK in the secondary display when
the measurement is between the high and low limit. It displays HIGH or LOW, as shown
above, for each measurement that exceeds the upper or lower limit. The beeper will beep
once (if enabled) for the first measurement outside the limits after an OK measurement.
For remote operation, the Meter can be set to generate a service request (SRQ) on the
first occurrence of a measurement outside the limits. See the Programmers Manual for
information on enabling SRQ for this test.
To set the high and low limits through the front panel:
1. Press J.
2. Press the MATH soft key
3. Press the LIMITS soft key.
4. Press the HIGH or LOW soft key as shown above to set the high or low limit
respectively.
To select the digit to adjust, press either <-- or -->.
