Section 4

Operation

4-14

One of the digits of the displayed calibration wavelength flickers.  This implies

that the MT9812B is now in the setting mode.  The value of the flickering digit

can be changed by pressing either the 

↑

 or 

↓

 key, and the flickering digit (which

can be inputted) can be changed by pressing either the 

←

 or 

→

 key.

(2)

Setting of the optical frequency to be calibrated

Operations

Remarks

Press the Prmtr key.

Continue pressing the key until the unit display

turns to “THz”.

Press the 

 or 

 key.

Select the input digit.

Press the 

 or 

 

key.

Set the value.

Press the Enter key.

The pressing this key establishes the setting.

One of the digits of the displayed calibration optical frequency flickers.

This implies that the system is now in the setting mode.

The value of the flickering digit can be changed by pressing either the 

 or 

key, and the flickering digit (which can be inputted) can be changed by pressing

either the 

 or 

 

key.

POINT

You can change the setting of the calibration wave-

length (optical frequency) without pressing the Enter

key, but the display continues to flicker.  It is therefore

recommended that the setting be confirmed by press-

ing the Enter key and the setting status be completed.

The conversion between the optical frequency and

wavelength is executed using the following formula.

λ

 = c/f, C = 2.99792458 

×

 10

8

 m/s (Light velocity in vacuum)

The execution result is displayed after rounding the

value at less than the displayed least digit. As a result,

the value obtained after the conversion process from

optical frequency to wavelength and the value from

wavelength to optical frequency may differ.

Example:

192.859 THz 

→

 1554.46 nm

1554.46 nm 

→

 192.860 THz
