Line: the calculated curve is point-point tangential path having no curvature.

It applies to sensors having step-variation in the data or having variation based

on straight slope and better linearity within a certain area. This arithmetic

requires that the data segment contains at least 2 groups of

reference data.

Curve: the calculated curve is an approximate result that has a certain

curvature. It applies to data has unfavorable linearity. This arithmetic

requires that the data segment contains at least 5 groups of

reference data.

Tip

For some sensor, the corresponding relation curve might both contain data

segment with good linearity (Line arithmetic is recommended) and data

segment with poor linearity (Curve arithmetic is recommended); in this case,

you need to use the segment function to define different arithmetic for

different data segment.

5. Store and Recall Sensor Configurations

Input reference data pairs (measurement and corresponding values) for the

arithmetic curve to be used and the interface as shown in the figure below is

displayed.

Press to finish the sensor property setting and returns to the User

interface. Then, press Done to enter the following interface.

 Press Save, the multimeter enters the store and recall interface and the

backlight of

goes on.
