(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:
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.
OPTICAL:
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.
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].
