Zero Reset Operation - Omron ZS-HL User Manual

Zero Reset Operation

When the zero reset function is used, the reference value "0" is registered as the height
and the measured value can be displayed and output as a positive or negative deviation
(tolerance) from the reference value. In RUN mode, the measured value can be reset to 0
at any timing during measurement.
Example 1: Using the height of sensing object registered as the reference value and the
tolerance output as the measured value
(reference value)
Example 2: Using the height of sensing object as the measured value with an offset set to 10
Example 3: Using zero reset to measure steps in sensing object (zero reset at each
measurement)
