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 displays OK in the secondary display when
the measurement is between the high and low limit. It displays HIGH or LOW, as show
above, for each measurement that exceeds the upper or lower limit. The beeper will beep
once 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 -->.
With the desired digit selected, press the soft key labeled -- to decrement the digit
or ++ to increment the character. The right most character is the multiplier. This
character can be set to p, n, ยต, m, k, M, or G.
5. Press ENTER to set the selected limit.
6. Press ENABLE to start the limits testing.
Note
Since the high and low limits are independent of each other, both hign and
low limit conditions could be satisfied by a measurement. In this case, the
Meter gives priority to the low limit conidition by displaying LOW and
setting the low bit of the questionable data event register.
Refer to the Programmers Manual for instructions on setting the limits remotely.
