Preset

It is possible to store/call 3 kinds of numbers.

Reference point detection

The reference point of the measuring unit can be detected, and the datum point can be relocated (during connection of measuring unit with a reference point)

Datastorage

The value displayed before the power was turned off and setting values are stored

Linear error compensation

A fixed compensation is applied to the measuring unit's count value. Compensation amount Standard: ±600 um/m (Expanded: ±1000 um/m)

Segmented error compensation

The movement range of the measuring unit with a reference point can be divided Into amaxlmum of 32 sections,

and error compensation Is performed for each of these sections, Compensation amount: ±600 um (at each sectlon)(LH71 only)
