Control Description
YES Status Bit - Autorange High Range
Logic High = M300M in high range
Logic Low = M300M in low range
YES Status Bit - System OK
Logic High = No instrument warning present
Logic Low = 1 or more alarm present
YES Status Bit - Bench Temperature Alarm
Logic High = Bench Temp out of spec
Logic Low = Bench Temp in spec
YES Status Bit - IR Source Alarm
Logic High = IR Source output too low
Logic Low = IR Source output normal
YES Status Bit - Wheel Temperature Alarm
Logic High = Wheel Temp out of spec
Logic Low = Wheel Temp in spec
