EXO2 Chl + BGA-PC Total Algae Sensor Sample Clauses

EXO2 Chl + BGA-PC Total Algae Sensor. There are two different parameters that must be calibrated independently; Chlorophyll and BGA-PC Total Algae. 3.10.1 This procedure calibrates Chlorophyll Relative Fluorescent Unit (RFU) or Chlorophyll μg/L. If the user has both units selected, then this procedure must be performed twice, once for each unit, to completely calibrate the parameter. 3.10.2 For 2-point calibrations, one standard must be clear water (0 μg/L), and this standard must be calibrated first. The other standard is a 625 μg/L Rhodamine XX xxx solution. Detailed instructions on preparation come directly from the EXO2 User Manual: 3.10.3 The solution is used in the calibration steps below. 3.10.4 μg/L – 1- or 2-point: This procedure will zero your fluorescence sensor and use the default sensitivity for calculation of chlorophyll concentration in μg/L. 3.10.5 Pour enough deionized water into the calibration cup to immerse the probe end of the sonde in the water. 3.10.6 Calibrate" -> "BGA-PC/Chlor" -> "Chl μg/L" -> "2-point calibration" 3.10.7 Enter 0 for first standard value and 66 for second standard value. 3.10.8 Start Calibration". Observe the readings under Current and Pending data points. While stabilizing, click the Wipe Sensors button to activate the wiper to remove any bubbles. 3.10.9 When data are Stable (or data shows no significant change for approximately 40 seconds), click "Apply" to accept this calibration point. 3.10.10 Next place the sensors in the Rhodamine WT standard. Click Proceed on the pop-up window. Observe the readings under Current and Pending data points. While stabilizing, click the Wipe Sensors button to activate the wiper to remove any bubbles. When data are Stable (or data shows no significant change for approximately 40 seconds), click Apply to accept this calibration point.
