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.
