Focus Meter FM1
The focus meter operates by analysing and measuring the picture detail at the centre of the picture. Since picture detail will vary from scene to scene, the meter automatically adjusts its display range to provide an optimum readout.
Operation
- Switch the unit on (SW1 in), the display will flash all LED’s in the absence of a video signal.
- Connect the camera output to the Focus meter, selecting high impedance (SW3 out) or 75W (SW3 in) to establish correct loading.
- Press and release RESET (SW2)
- Slowly rotate the camera focus ring fully in both directions taking care not to obstruct the lens from its normal view.
- Set the lens for correct focus by rotating the focus ring for maximum LED readout.
Notes
If the scene changes during adjustment, due to accidental camera movement or inadvertently blocking the lens for example, the display range may require resetting by repeating the above instructions from stage 3.
