Relative Function

The relative function is also called Null measurement, which is the
difference between a stored null value or a reference value and the
measured value. This relative function is applicable for all multimeter
measurement except the diode test and continuity test. To turn on or off
the relative function, press F2 in each respective multimeter function
submenu.
Example:
Obtain a 1.177 k
reference value by turning on the Relative function. The reading will be
displayed as 0
reading obtained is 1.766 k
0.586 k
Relative value = Measured value - Reference value
