(2) Registering local calibration settings
You can use the [CALIBRATION SETTING] screen to register local calibration settings (calibration settings that are locally
saved in the DS-L4) as the basis for displayed scales and measured lengths.
Local calibration can be set in OPTICAL or MANUAL mode. You can register a maximum of 14 local calibration settings
(from M1 to M14). You can use any one of these settings.
Registration modes of local calibration settings
You can register a calibration setting in one of two modes: MANUAL and OPTICAL.
 MANUAL:
 OPTICAL:
Required tools
Prepare the following tools for registration using the [MANUAL] setting.
 Object of known length
Registration in MANUAL mode
To perform calibration by displaying an object of known length and specifying its length:
1 In the [TOOL SET] screen, tap [CALIB SET].
2 Select one of the local calibration setting numbers (M1
to M14) as the container of local calibration data, and
then tap [MANUAL].
3 Display an object of known length on the screen.
4 Draw a calibration line ((A)-(B) in the figure) along the
object on the screen.
Use a mouse to perform this operation.
Specify the starting and ending points. A line is drawn
between them. To try again, tap [ERASE], and then redraw a
line.
5 Tap [VALUE], and then enter the length of the object.
Range of values that can be entered: 0.01 to 99999.99
To use the software keyboard, tap [&123] and show number
keys.
Do not tap [X] on the software keyboard. If you do so, the
software keyboard disappears with the entry field displayed.
To redisplay the software keyboard, select the entry field.
6 Tap [UNIT], and then select the unit to be used.
To clear the value that has been entered or calibration line
that has been drawn, tap [ERASE].
7 Tap [OK].
Preparation for Using the Annotation Function and Measurement Function
In this mode, you display an object of known length, and specify the length on the screen.
The specified value is used as the calibration value.
In this mode, you enter the magnification of the optical device (such as a microscope). The
DS-L4 then calculates the calibration value from the entered value.
