Reading range of X-Rite 361T?

Does anyone know the reading range in nanometers of the X-Rite 361T in the UV mode? In another forum someone mentioned that the 361T does not read very far into the UV range, and misses entirely the range from 360-390 nanometers. He suggested that a reading that I made of Pictorico substrate might not be very reliable, thinking that I was using the 361T. However, I use a Gretag D-200 II which reads at 373 nanometers in the UV, an almost perfect spot for both dichromate and iron based processes.

I called X-Rite at one point and they told me that it reads in a narrow range of 375 to 385 with a peak at 380.
