It measures Free & Total Chlorine, Cyanuric Acid, pH, Iodine, Bromine, Low Range Iron and Turbidity. In the colorimetric mode, the user can select either factory preprogrammed calibration settings or calibrate the meter using customized calibration values based on the concentration or relative absorbance of the sample. Calibration data is also stored in a non-volatile EEPROM. In the turbidity mode, periodic recalibration of the meter with primary standards according to regulatory requirements or personal experience is suggested. Turbidity ranges are 0.009.99 NTU and 10.0-50.0 NTU. C 102 complies with G.L.P. Standards (Good Laboratory Practice), that is: · When switched on, the LCD displays all segments (display check). · Battery status is monitored during every measurement cycle warning the user if the batteries become weak. In addition, C102 will turn itself off before low voltage causes erroneous readings. · It utilizes a real time clock and recalls calibration data such as date, time and calibration values. To facilitate field tests, the meter provides a logging mode. In this mode, the user can store up to twenty five time-tagged measurements in RAM and scroll the memory at any time. There are eight keys for the different operationals modes. The large Liquid Crystal Display is dual-level: the upper level has four digits and can display the measured parameter in hundredths. The lower level has three characters and indicates current mode (e.g. F CL for free chlorine or TR for turbidity). Different LCD segments indicate low battery, logging mode, date, time, etc. A pure Green LED has been utilized as a light source for both turbidimetric and colorimetric measurements. A silicon photocell is used to receive transmitted light from colorimetric channel while another photocell receives scattered light from the turbidimetric (nephelometric) channel. In order to measure colorimetric parameters, all the operator has to do is zero the blank sample and then add 1 packet of reagent (for Bromine, Chlorine, Cyanuric Acid, Iodine and Low Range Iron) or 0.2 mL of Phenol Red (for pH). After placing the cuvet back in the meter and pressing READ, the measurements are shown directly on the LCD. The instrument operates with four AA batteries and may be operator-programmed to turn itself off automatically after 10, 20, 30, 40, 50 or 60 minutes of inactivity. C 102 and all accessories such as sample vials, reagent pillows, primary standards, can be easily stored in the optional carrying case (HI 710031). 4 5 In Progress". The upper level also indicates the concentration or turbidity of the sample, as well as different diagnostic modes, such as "-BA-" for low battery. 2) Secondary LCD: The three-digit LCD shows the current mode of measurement that is "F CL", "t CL", "CY", "PH", "Id", "Br", "L FE", "tr", and diagnostic or calibration modes, such as "d 11", "2 Fn", "5 c1". Indicates that the upper level of LCD is showing the current date, the date of last calibration or the date of logged measurement in memory. Indicates that the upper level of LCD is showing the current time, the time of last calibration or the time of logged measurement in memory. Blinking segment warns user of low battery voltage. If intermittent, it indicates that the user is in the scroll mode viewing the logged measurements. If fixed, it indicates that the meter is in the log mode and every reading taken will be stored in memory. 10 7) ON/OFF key: 8) ZERO / Turns the meter on and off. key: In ion specific (colorimetric) mode, it zeros the sample. In calibration and diagnostic modes, it functions as ENTER (not used in turbidity mode). key: Takes the measuremnt of concentration/turbidity of the sample which is shown on the LCD. In diagnostic or calibration mode, shifts the flashing digit to the right. If pressed during calibration, the calibration procedure will be aborted and the last calibration data will be reinstated. If pressed together with the ALT key for less then 3 seconds, the diagnostic mode will be entered. If pressed together with the ALT key again, the meter will quit diagnostic mode. If pressed for more then 3 seconds, an intermittent "CAL" prompt will appear on the upper LCD level and the calibration procedure is entered. 9) READ / 3) DATE: 10) CAL key: 4) TIME: 5) LOBAT: 6) LOG: 11) GLP/Abs key: In ion specific mode, it will toggle concentration/absorbance readings on the upper LCD. In turbidity mode, date, time and the two calibration values of the current mode will be 11 shown. If pressed in time/date setup mode, the meter will quit current mode without making any changes to current time/ date. 12) key Scrolls upwards through the parameters to be measured. In calibration/diagnostic mode, increments the blinking digit by one. If pressed together with ALT while the meter is in logging mode, the upper LCD will show the data (date/time/value) in the memory. Alternative functions. Scrolls downwards through the parameters to be measured. In calibration/diagnostic mode, decreases the blinking digit by one. If pressed together with ALT while the meter is in logging mode, the upper LCD will show the current lot number.
