[GreenKeys] Model 15 Typical Operational Bounds on the Range Finder

[Mike Douglas]

According to a Model 15 technical manual, "A teletypewriter, in good condition, should give a lower scale reading between 10 and 15, and an upper scale reading between 85 and 90." I'm curious what range finder bounds most of you get with your restored Model 15s. These limits are affected by loop voltage, current, the data  source, etc., so include this information with your bound numbers. Thanks!
