Tip 5: Limit Test
Limit test is an extra value-added
feature of the 34450A. When the
limit operation is enabled, the
DMM instantly notifies you if a
measurement result falls outside the
high or low limits you establish prior
to making a series of measurements.
Upon setting the 34450A to limit
operation, the DMM's display is
divided into four segments as shown
in Figure 5. The two segments on
the left are for setting the high and
low limits. The upper right segment
displays the last measurement and
the lower right segment displays the
limit results; whether it is pass, fail
low, or fail high.

Conclusion
The 34450A 5½ digit multimeter
offers superior ease of use on the
bench and for remote operations.
Whether your application requires
general purpose measurements, or
fast throughput and programming
speed, using the tips provided will
help you optimize the capabilities
of your 34450A DMM.
Limit operation is extremely useful
for manual operations. There are
many simple and low cost production
tests require only one DMM to
perform a specific test. For example,
measuring the voltage across an LED
to determine whether it is within
its tolerance can be done easily
using the limit test function of the
34450A. The 34450A displays "PASS",
"FAIL-LO" or "FAIL-HI" based on the
limits set. Apart from displaying the
measurement value with a pass or fail
identification, the 34450A beeps to
alert the operator when a measured
value falls outside the set limits. You
can put the 34450A into the limit
operation by pressing [Shift] > [Math].
