Using Measurement Limit Indicators
The Lo Limit and Hi Limit functions are used to define a measurement
“window.” You can set a high limit, a low limit, or both. When limits are
assigned, Lo, Hi or both are indicated on the screen.
A measurement that goes above or below the defined limits causes
three things to happen:
1. A message appears at the top of the screen indicating a limit was
exceeded.
2. The Lo or Hi indicator flashes.
3. The beeper beeps (if it is has been enabled in the INSTRUMENT
CONFIGURE screen).
Limits are helpful when you can’t watch the Test Set’s display while
you are making an adjustment on the equipment you are testing or
repairing. They are also a convenient way of alerting you to long-term
measurement drift.
To set high and low limits
Step 1. Position the cursor in front of the unit-of-measure for the
measurement for which you are setting limits.
Step 2. Press and release the
Shift key, then the down-arrow key to
access the Lo Limit function, and enter the measurement’s
low-limit value and its unit-of-measure.

Step 3. Press and release the Shift key, then the up-arrow key to access
the
Hi Limit function, and enter the measurement’s high-limit
value and its unit-of-measure.

1. The fundamental unit for the limits does not have to be the same as the mea-
surement’s units. For instance; when measuring AC Level in Volts, you can set
high and low limits in units of dBm.
