For any given shutter speed and ISO setting, "Over" will be displayed when the measured light value requires an f-stop
setting that is greater than the maximum available f-stop (f/128). "Under" will be displayed when low light requires a
setting lower than the minimum f-stop (f/0.5).
Example of Over Exposure Display

When the display range is exceeded and "Over" appears, make one of the following adjustments until a suitable
f-stop appears on the measuring display.
•
Change the T (shutter speed) to a faster setting.
•
Set the ISO sensitivity to lower setting.
•
If possible, lower the output power of light source, and take another measurement.
2) When under exposure "Under" is displayed:
When the display range is exceeded and "Under" appears, make one of the following adjustments until a
suitable f-stop appears on the measuring display.
•
Change the T (shutter speed) to a lower setting.
