Lightmeter submenu
The "LIGHTMETER" submenu offers you the choice between three metering
patterns: INTEGRAL, SMALL SPOT or LARGE SPOT.
The Lightmeter function is only enabled if Brightness has been set to
"Automatic" or "Low Light Auto".
Integral:
The exposure is measured and averaged across the full video image. This
measurement is recommended for surgical fields that are fully and evenly lit.
Large Spot:
The exposure is measured in an area in the image center. This measurement
is ideal for working with an eclipsed surgical field edge (resulting from
a reduced illuminated-field diameter).
Small Spot:
The exposure is measured in a very small area in the image center. This
measurement is suitable for work in narrow channels when an extremely
small illuminated-field diameter is being used.
However, if the object of interest is not located in the image center, the
SMALL SPOT setting usually does not provide the desired exposure result.
In this case, select either a larger area (INTEGRAL or LARGE SPOT) or use the
manual exposure mode.
