X-Rite 309 Compatible w/ B&W Negs?

[jlphotos]

I recently purchased an X-Rite 309 densitometer, and didn't do all of my

research prior to buying. I just discovered that it's a color densitometer, and

I'm wondering if anyone has any experience with this densitometer, and if so,

could tell me how to make density readings of black and white negatives with it

(if possible). Thanks!

I haven't used this model, but you can find the manual at:

Either use the colour which closest resembles the enlarging papers spectral peak-sensitivity or your densitometer has a "vis" setting for white light (most do) and you can use that.
