measurement. Diopter should be adjusted for

 

the eyesight of the person who will be taking

 

measurement. If diopter is not adjusted before

 

 

focus measurement, correct measurement value

 

may not be expected. This is because the focus

 

is actually off even if you think it is correctly in

 

focus. In addition, if diopter is not correctly

 

adjusted, you may see the aperture moving

 

depending on viewing angle.

Setting

Setting of Synchronization

The synchronized measurement refers to measurement mode where measurement is made in the same timing as periodical light source pulse frequency, such as vertically synchronized frequency for the display device.

[INT SYNC]

The internal sync measurement mode is used to measure the display equipment without the input of vertically synchronized signals to the body, or to measure flicker light from a light source such as a fluorescent light. Input the frequency of vertically synchronized signals for the display equipment, or the commercial frequency (50 or 60 Hz) for flicker light from a light source such as a luminescent light. The optimal integration time is automatically set based on the input value and the brightness of the object. For this reason, enter the correct frequency value to two places of decimals.

However, if the vertically synchronized frequency of the display equipment is not clear, accurate measurement will not be possible with an inaccurate frequency setting. In this case it is recommended to select [NO SYNC] mode without sync measurement (at 60 Hz of frequency), but to select [MULTI-NORMAL] mode or [MULTI-FAST] mode for the measurement time (refer to p. 29).

[EXT SYNC]

The external sync measurement mode is used to measure the display equipment after the line input of a vertically synchronized signal through the input terminal for vertically synchronized signals to the body. The optimal integration time is set automatically, based on the frequency of vertically synchronized signals and the brightness of the object.Input CMOS (5V) Level of the input signals.

* Range of synchronized frequencies : 20.00 to 200.00 Hz

* Factory default setting : NO SYNC
