Once you calibrate the reference length, you will have a simple means of measuring distances. 
You can save seven calibration values for each objective or measurement condition and reuse 
saved values by calling them up the next time you perform a measurement. 
 
 
 
3.4.1 
Performing Calibration and Saving Values 
Before measuring the length of anything, you must first calibrate the reference length. Be aware 
that you cannot perform measurement if you skip the calibration process. 
There are two ways to calibrate: You can use a subject of known length 
, or you can use the 
magnification of the objective and relay lenses 
. You can switch between these two methods 
by right-clicking the    Calib.    icon. (The icon will change accordingly.) 
 
 
         
 
 
 
 
 
<When using a subject of known length> 
 
NOTE:  If the microscope connected to your system is the Nikon 80i/90i microscope, 
set the magnification of the digital imaging head optical zoom to x1.0 before 
calibrating. 
1) 
Select the number in which you want to save the calibration value (from    s1    through   
 s7 ). 
Drag the mouse pointer over one of numbers   s1  through  s7 , and the calibration 
information for that number will be displayed in the Info area for your confirmation. 
2) 
Press    Calib.    to bring up a calibration screen like the one shown below. 
 
 
 
 
 
3) 
Draw a calibration line about the length of a specific subject on the image that you want to 
be the reference. 
Click the mouse button at the starting point of the object to be measured. To draw a line, 
hold the mouse button while you drag it to the end point, then release the mouse button. 
To redraw a line, use    Clear    to erase the line you’ve just drawn. 
4) 
When you have finished drawing a line, click the number input box to display a numeric 
keypad.  
After entering any number, press    Ent . 
5) 
Select the unit of measure. (nm, µm, mm, cm) 
6) 
If you want to attach information to the calibration value you’ve created, click the Info 
input box and enter text for the information you want to attach. This information will 
prove helpful because you can confirm Info when you call up the calibration value at a 
later time. 
7) 
Check the Set number to see if the calibration number is correct and press    Save    to save. 
Unless you enter a numeric value and a unit, you cannot press the    Save    button. If you 
want to recalibrate, use    Clear    to erase the current calibration value before saving it.
