Select [AREA] from [BASIC] on the program
mode screen.
The area setting screen appears.
2 Select [AREA 1].
3 Select a measurement method for [AREA1].
Select from among [AVG], [MAX], [MIN] and
[DIFF].
4 Select [AREA2].
Select a measurement method for [AREA2] in the
same manner.
5
Press the [ENTER] button.
The areas are fixed.
[DIME] (Area measurement) can only be set for Area2.
However, it cannot be set when a calculation (A1–A2
and A1+A2) is set for [MEASUREMENT].
Area setting for the area measurement
Switch the upper and lower limits of Area 1 and set
both ends of the scanning range in Area 1. Measure
the area of Area 2 using the approximated line of
Area 1 as a reference.

This section describes area, scanning, dark, and
smoothing.
The following measurements can be performed
using the data that is obtained in the area
specified within the scanning range.
Two areas can be set: [A1 (Area 1)] and [A2 (Area
2)].
Using the respective values measured in [A1] and
[A2], following measurements can be calculated.
AVG Measures an average value
DIFF Measures a differential between the maximum
and minimum value
MIN Measures a minimum value
MAX Measures a maximum value
DIME Measures an area (µm 2 or mil 2 )
