[. . . ] 5. 34 NTU: For pH, add 0. 2 mL of HI 93710-01: For Chlorine, Iodine and Bromine, add the content of their respective packet: 1x COLORIMETRIC MEASUREMENTS Turn the meter on. After the initialization routine, the LCD will display: Use the and keys to choose the desired parameter: F CL CY Id L FE Free Chlorine Cyanuric Acid Iodine Iron t CL Total Chlorine PH pH Br Bromine For Cianuric Acid only, add the content of one packet of HI 93722 reagent to a beaker filled up to the 25mL mark with unreacted sample up to the 25 mL mark. Stir gently to mix and then fill the cuvet up to 1. 5 cm (¾") below the rim with 10 mL of the reacted sample. 1. 5 cm Measuring Chlorine, Cyanuric Acid, pH, Iodine, Bromine Fill the vial with the sample (blank). The surface of the vial should be clean and scratch free. Insert the blank sample into the cuvet holder and ensure that the notch on the cap is positioned securely into the groove. Press ZERO. Replace the cap, shake the cuvet and allow a few seconds for color to develop. for Total Chlorine, Bromine, Iodine, and 45 secs. Insert the reacted sample into the cuvet holder and ensure that the notch on the cap is positioned securely into the groove. Press READ. The meter will show "SIP" for a few seconds and then the concentration: 16 17 Measuring Iron Fill one graduated mixing cylinder up to the 25 mL mark with deionized water. Add the content of one packet of HI 93746 TPTZ reagent, close the cylinder and agitate for 30 seconds. This is the blank. 12 9 Add the content of one packet of HI 93746 TPTZ reagent, close the cylinder and agitate for 30 seconds. 30" 3 6 12 9 30" 3 6 Fill a cuvet with 10 mL of the blank up to 1. 5 cm (¾") below the rim and replace the cap. 1. 5 cm Fill a cuvet with 10 mL of the reacted sample up to 1. 5 cm (¾") below the rim and replace the cap. This is the sample. 1. 5 cm Insert the blank into the cuvet holder and make sure that the notch on the cap is positioned securely into the groove. Press ZERO. Insert the reacted sample into the cuvet holder and make sure that the notch on the cap is positioned securely into the groove. Turn the meter on and press both ALT and CAL momentarily. + The LCD will show four dashes on the upper and "d 00" on the lower part of the LCD with the second "0" blinking. Using the , and keys change the lower row of the display to show "d 21". Insert the previously prepared 50 NTU standard into the cuvet holder and make sure that the notch on the cap is positioned securely into the groove. Press . The display will blink "-Lt-" for several seconds, indicating that the LED is being adjusted for the turbidimetric channel. Afterwards, a sequence of numbers between -511 to 512 will appear on the upper part of the LCD indicating different levels of LED light intensity. In approximately one minute, the adjustment will be made and the calibration data stored in the non-volatile memory. The display will show four dashes again indicating the end of the span calibration procedure. Press the ALT and CAL keys together again to leave the diagnostic mode. + Two-point customized calibration To enter the turbidity calibration mode, the meter should be in "turbidity" mode. Use the and keys to set the lower level of the LCD to "tr". To enter the calibration mode, press and hold the ALT and CAL keys together for at least three seconds. [. . . ] Make sure the cuvet is capped and placed properly in the holder, and that ambient light does not reach the photodetector. If the problem persists, contact your dealer or the nearest Hanna Office. If the error message appears again, contact your dealer or the nearest Hanna Office. Check the measuring procedure and verify the concentration of the sample to ensure that is not too high. BATTERY REPLACEMENT A "LOBAT" indication appears on the lower right hand side of the display when the batteries are weak and require replacement. [. . . ]
