Making Relative Meter Measurements
A relative measurement displays the present
measurement result relative to a defined reference value.
The following example shows how to perform a relative
voltage measurement. First obtain a reference value:

adjust the reference value (see
step 5 below).

Now the large reading is the actual input value minus the
stored reference value. The bargraph indicates the actual
input value. The actual input value and the reference value
are displayed below the large reading (ACTUAL: xxxx
REFERENCE: xxx), see Figure 18.
You can use this feature when, for example, you need to
monitor input activity (voltage, temperature) in relation to a
known good value.
