1. Exhaust waste liquid To waste liquid trough Structure diagram of cleaning trough 5 5 Calibration the Pumped Liquid Amount of Flowcell Calibration for the pumped liquid amount of flowcell is very important it can affect the aspirate amount and the position where the reaction liquid passes through the flowcell and decide whether air or reaction liquid reaches the flowcell during color comparison so it affects the test result directly It can be carried out according to the procedures below 1 Start up the analyzer to enter the backdoor program 2 Calibration the aspirate amount of pump first move X axis to one reaction after adding 450ul water to the reaction position feed Z axis probe and click Quantitative Aspirate after reaching the position of quantitative aspiration When the aspiration is complete observe the amount of residual liquid in reaction cup which should be less than 50ul If it is more than 50ul the designation factor of pump can be increase for increasing the aspiration amount If air is aspirated during aspirating liquid the designation factor can be reduced 3 And then calibration the additional liquid amount You should calibration according to the minimum reagent amount of the analyzer Now we designate as 400ul After adding 400ul high concentration Page 41 of 47 pages RT 200C Plus Service Manual color solution generally we use K2Cr207 solution or Cre reagent to a reaction position mo2. 1 2 owitch off the analyzer and lift the rear cover of the analyzer Move the Sampling head to the original position the sample probe just faces towards the waste liquid hole At this time observe the positions of X axis positioning optical coupler and limiting baffle the limiting baffle should just block the middle of the optical coupler If not you can adjust the position of limiting baffle After the adjustment start up the analyzer to check the X axis position during start up self test If an offset exists you should go on adjusting If the probe feed position is accurate the regulation is complete close the rear cover of the analyzer 4 15 Regulation of X axis Zero Point The positioning of Y axis zero point can be carried out by limiting baffle on Y axis together with Y axis positioning optical coupler on Z axis control board When it moves to the limiting baffle and block the detecting optical coupler Z axis control board detects the voltage change feedbacked by optical coupler and determines the zero point is reached and stops moving Regulation of Y axis positioning is mainly for limiting the position of the baffle Page 34 of 47 pages RT 200C Plus Service Manual Y axis positioning optical coupler Y axis positioning Y optical coupler Y axis limiting 7 per og l i baffle Y axis limiting baffle Fig 1 shows the installation method of Z axis control board of the old version Fig 2 sho
