Discussion questions: 

  1. If a police officer adjusts any of the grey variable resistors that adjust internal standards 100, 200, and 300 is it necessary that the internal standards be confirmed using simulators with SAS solutions at each of 100 mg/100mLs, 200 mg/100mLS, and 300 mg/100mLs?

  2. If channel voltages and internal standards are adjusted following a filter wheel motor change should acetone detect and acetone subtract variable resistors (top right two blue rectangles) not also be adjusted?

  3. Notice the small resistor near the top, to the left of the blue rectangles, and immediately above the two wires from the filter wheel motor. Click on this resistor for more information. Can this resistor be removed and replaced by soldering from this side of the processor board or from from the top edge - the filter wheel slot or must the whole processor board be removed and replaced after soldering is complete?
