The Use of Relative Value Mode
The REL mode applies to all measurement functions except frequency and duty cycle measurement. It subtracts a stored
value from the present measurement value and displays the result.
For instance, if the stored value is 20.0V and the present measurement value is 22.0V, the reading would be 2.0V. If a new
measurement value is equal to the stored value then display 0.0V.
When REL mode is selected, the Meter will switch from Autoranging to Manual ranging except under capacitance testing
mode.
