SETTING MEASUREMENT AREA Measurement areas of o 25mm and o 50mm can be selected by extending or retracting the lens barrel. The o 25mm measurement area can be used for measuring LCDs with 2 - inch or greater diagonals: the o50mm measurement area can be used for measuring LCDs with 4 inch or greater diagonals.
Set the measurement area : Using a slotted screwdriver, loosen the lens - barrel locking screw. Slide the lens barrel to the position corresponding to the desired measurement area. The lens barrel should be slid in the desired direction until it stops. Extending the lens barrel fully sets the o 25mm measurement area: retracting the lens barrel fully sets the o 50mm measurement area. Use the screwdriver to tighten the lens - barrel locking screw and lock the lens barrel in position. Changing the measurement area also changes the measurement angle. this may result in differences between values measured with the o25mm measurement area and those measured with the o50mm measurement area to the viewing - angle characteristics of the LCD. For this reason. it is recommended that the measement area be constant for all measements.
2. Move in either direction until it stops.
