ZERo button: Relative display function
The ZeRo mode displays the difference between the actual reading and a reference
value. it may be used with any function or range; however, the range must be
set manually. To make a relative measurement first establish a reference value
by measuring a value and then pressing the ZeRo button after the reading has
stabilized. This stores the measured value as the reference and sets the display to
zero. The meter subtracts the reference value from subsequent measurements and
displays this difference as the relative value. Measurement values greater than
the reference value will be positive and values less than the reference value will
be negative. To exit the Zero Mode, press and hold the Zero button for 2 seconds.
