<p>Hi there<br>

This meter comes with three dials<br>

- one for flash photohgraphy<br>

- one for standard photograpy <br>

- one for long exposures to consider the schwarschild factor<br>

Myself here in SYdney I would like the two discs I am missing..... the flash and the long.<br>

<p>Hi there<br>

For as far as I know that is not necessary.. There are two ways of measuring the light....<br>

- measure on a grey chart which gives you a 'middle value' this is used for subjects without a large range of colours and shadows<br>

- measure white and black value where you still want details before absolute pure black/white and combine them on the dials.<br>

The calibration would be something that needs to be done as maintenance or service by Gossen. You need to use the appropriate type of well charged batteries and clean contacts etc... and should not have anything to do. <br>

The gray chart is for sure not used to calibrate... but for subjects rather monochromatic. <br>
