(5)Monit

Waveform monitor mode is activated. The Focus monitor and B/C monitor modes are set alternately by clicking the button.

At the first click, a waveform is displayed for monitoring the focus. The magnification is set at 1,000×. Focus the image so that the waveform shows sharp peaks.

The next click changes the mode to B/C monitor. A waveform and reference lines are displayed for monitoring contrast (amplitude of the waveform) and brightness (vertical level of the waveform).

When the maximum and minimum values of the waveform are adjusted to fit within the upper and lower reference lines, appropriate brightness and contrast will be obtained. To terminate the Focus monitor and B/C monitor mode, click the Cancel button in the message dialog shown while in the monitor modes, or click one of the scan speed buttons. Refer to <3.5.4 Image Brightness and Contrast Adjustment> and <3.5.5 Focus and Astigmatism Correction>.
