How to use this color analyzer? Pls help.

I brought this Fujimoto color analyzer on Yahoo Japan but it didn't come with a manual. only few low res pics were found after seraching google.

I know most color analyzers have similar work flow (make perfect print first, analyze the perfect print and save CMY values into analyzer 's memory as a reference). But this one comes with a "Sensitivity " knob and "Density High & Low" switch.

Anyone has experience on this machine or user manual. Thanks and happy holidays

What does the knob do when you turn it?
It is a Null meter, so, I suspect that is the knob to null the meter.

I think you would use the sensitivity knob to zero the Cyan channel from the meter, before zeroing the Magenta and Yellow channels using the enlarger filters. This will compensate for any difference in negative density. Switching from High to Low will depend on the density and the degree of enlargement - if you are on 'Low' and run out of sensitivity, switch to 'High', it shouldn't affect the colour settings.

The density "High/Low" switch obviously works the same as with lightmeters for taking, where you can set the sensitivity and then have to do the reading at one of two different scales.
