Making relative measurements (Null)
When making relative measurements, also called null, each reading is the
difference between a stored (selected or measured) relative value and the input
signal.
One possible application is to increase the accuracy of a resistance measurement
by nulling the test lead resistance (test leads shorted). Nulling the leads is also
particularly important prior to making capacitance measurements (test leads
open).
Press the key to enter the relative mode and store the display reading as a
reference value. The LCR meter will then display all subsequent readings relative
to the reference value.
