Grafikon will not give out any schematics, or technical service
information for this meter. To calibrate it, you would require the
proper calibration filter groups, reflection references, and light
source. It is a fairly complicated arrangement to calibrate a colour
meter.

If you are using the meter in-house as a reference tool for colour
repeatability, and not using it to reference your products to facilities
outside, the calibration would not be critical in this case. If you are
going to reference your product to other facilities using colour
standards, that are using their own colour meters, then calibration will
be a very strong issue.

Hi, Does anyone have any information regarding a Grafikon Colour
Analyser.
There is no model number on the case, but there are two analogue meters
on
the front panel, measuring R and B wrt Green. There are two thumbwheel
decade switches (trims for r and g), and three press buttons for Lum,
H/L
and times 3 gain. The unit seems to basically work, but if anyone has
any
information, circuit diagram or alignment information, that would be
most
helpful. Even the operating instructions would be a start.


Thanks in advance.

Trevor.
