The case of the base unit contains the transmission lamp. The

The top of the base unit serves as a platform, on which the film
rests during measurement.
The measuring head is mounted to the base unit by a precise
bearing. The integrated spring pushes the measuring head in the
upper position. The head contains the sensing electronic, below
of it the probe is mounted.
The transmission lamp and the displays are activated when the
measuring head is lowered.

If the minimum sensitivity of the system is reached or if the
measuring head is depressed to fast, the display will flash ‘-888’.
If an error occurs during measurement, it will be displayed in the
following way: E XX where XX is the number of the error. The
only error that can be serviced by the user, is 'E 01' i.e. there is to
much light at the probe. This will occur if the aperture (TD1) or the
probe (TD2) is removed . In this case simply install the aperture or
the probe and measure again. In all other cases please consult
the manufacturer.
The LED's beside the 3-digit display show the selected
measurement mode while the measuring arm is lowered.

The 'MIN' switch resets the density display to value 0.00, it is only
