equipped with the ASX-200.
Service Data
ID result displays the identified gas or mixture
Total % is the anesthetic agent concentration measured by ASX bench.
Rel % is the relative percentage of each measured agent in the mixture.
Noise value should be less than 80. Check the value only when no gas is fed and after a minimum
of one minute stabilization time.
Temp C is the temperature inside the ASX unit.
AGC (Automatic Gain Control) should be between 100 and 3500.
Motor DAC is a motor speed control voltage, 100...3900, and Motor Fluct is the speed
fluctuation, should be < 200.
Alc comp val is the compensation factor for alcohol content measured during halothane, enflurane
or isoflurane measuring. Sta shows the status of compensation, 0 means off, and 1 means on.
The value without a leading text is for factory use only.
Peak normal, Peak mirror give the place of the spectrum’s peak in the channel numbers. The peak
normal value should be 10.3- 10.7 with calibration gas R23, and 12.9-13.1 with R22. If the value
is not within the range, the gas calibration must be performed (see User’s manual for instructions).
Time offset is the time between motor synchronization pulse and filter 0° angle. Fact is the factory
value for it, EEPRO is the user calibration result, stored in the ASX, and RAM is the user calibration
result, stored in the gas mother board.
Spectrum values tell about the scales of the spectrum display.
