Omega Speaker Systems manual Thermocouple Input, Gain = OME-A-82X Gain X OME-DB-889D Gain

3.3. The Thermocouple Input

The OME-DB-889D can accept thermocouple sensor to measure temperature. The OME-DB-889D should be set to different gain value if use different thermocouple type.

If you are usingOME-A-82XPGL series multi-function bard to linked OME-DB-889D you have got the gain as:

Gain = OME-A-82X Gain X OME-DB-889D Gain

OME-A821PGL Gain = 1 , 2 , 4 , 8						OME-DB-889D Gain = 0.5 , 1 , 5 , 10 ,
50 , 100 , 1000
