Liquid sense sensitivity adjustment (PLL circuit)
SAMPLE ROTOR:
• Turn “P1” to the extreme left (CCW) position (very insensitive).
• Put a dry and empty Sample tube in the Rotor on position “2”, surrounded by
empty paediatric adapters on position’s 1, 3, E3, 4, W, B and S1.
• Select in the service menu, sample arm and reset the sample arm [F1].
• Turn the sample arm into the Sample tube on position “2” [→][→][→][↓].
• The liquid detection has to be “NO”.
• Turn “P2” to the right (CW) position until the liquid detection changes to a “YES”.
Now turn “P2” to the left (CCW) until the bit changes again to a “NO”.
• Turn “P2” 360° (one complete turn) to the left (CCW).
REAGENT ROTOR:
• Turn “P2” to the extreme left (CCW) position (very insensitive).
• Put an empty 5ml bottle on position “28”, surrounded by water filled bottles on
position’s 15, 24, 25, 26, 27, 29, 30, 31, 32, 1 and 16.
• Select in the service menu, reagent arm and reset the reagent arm [F1].
• Turn the reagent arm into the empty bottle on position “28” [←][←][←][←][↓].
The liquid detection has to be “NO”.
• Turn “P1” to the right (CW) position until the liquid detection changes to “YES”.
Now turn “P1” to the left (CCW) until the bit changes again to a “NO”.
• Turn “P1” 360° (one complete turn) to the left (CCW).
Check also for some other positions if the liquid sense is working well.
