Bosch RTT 100 Smoke Meter Literature Help

[cobrajetken]

I am with Stony Brook University's Department of Mechanical Engineering. We recently acquired a used Bosch RTT 100 Smoke Meter. Unfortunately we did not receive any manuals with it. I have been trying very hard to locate an owners/operating manual for this unit which we hope to use in our engine lab. I was wondering if you might have any suggestions on where I may find such any literature on this meter. We hope to use this smoke meter on a deisel engine for educational purposes. Any help would be greatly appreciated. Thank You.Ken Testa (631-902-4254)
