5-3. Out of Displayed Range or Measuring Range
(*This example explains what needs to be done in Cord (PC) Flash mode.)
5-3-1. When Displayed Range is Exceeded
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
Example of Under Exposure Display
1) When over exposure “Over” is displayed:
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.
•
Set the ISO sensitivity to higher setting.
•
If possible, raise the output power of light source, and take another measurement.
5-3-2. When Measuring Range is Exceeded
When the amount of light is outside the measuring range of the meter, the “Over” and
“Under” displays will appear and blink. When this happens, adjust the brightness level
to obtain a measurement.
When brightness exceeds
measuring range
When brightness is under the
measuring range
