1. CLEANING MEASUREMENT CELL In order to maintain the maximum reliability of measurements itis recommended to periodically clean the measurement cell In fact the measurement cell could collect sediment or de velop a film growth on the inside walls Thorough cleaning with a dilute acid solution and a cotton swab is recommended monthly Depending on sample con ditions at individual locations and absence of input filters it may be necessary to clean the cell on a weekly basis This can be determined by observing the cell condition when reagents are changed It is also highly recommended to clean the cell every time you turn the meter off In such a way scaling and molds growth are prevented Otherwise subsequent cleaning might become more difficult For cleaning procedure remove the plastic cap placed on the top of the measuring cell Add a few drops of 19 2N Sulfuric Acid solution or alcohol to the cell Allow sulfuric acid to stand in the measuring cell for 15 minutes to dissolve any foreign materials adhering to the cell walls Wipe the cell interior with a cotton tipped swab After wiping open the drain port to empty the measuring cell from the cleaning solution 47 RELAY TEST In the relay test mode all three alarm relays close for about one second 1 Press DIAG The display will show the last diagnostic mode and the eee digit will blink A araro E DIAG 7 mAN O LOLE 2 Enter code 501 using the2. 5 MECHANICAL DIMENSIONS 6 FUNCTIONAL DESCRIPTION 7 LED DISPLAY INDICATORS AND KEYBOARD 8 SPECIFICATIONS 0 0 00000 00005 10 OPERATING DESCRIPTION 12 Method of analysis 00 13 INITIAL PREPARATION AND INSTALLATION 14 Installation Personnel 14 Location of the Instrument 14 Hydraulic Connections 14 Installing the Input Filter 16 Installing the Pump Tubes 16 Electrical Connections 18 SHARTHUP weres aa rI a Gana wa oe hae a 22 Instrument Power On 00 005 22 Display Brightness 00 22 Minimum and Maximum Concentration 23 Sampling Rate 000000 24 Priming the Reagent System 24 ANALYZER PROGRAMMING 26 Proportional Dosing 06 26 Concentration Setpoint Alarm Setting 28 Recorder Output Span Setting 30 Standby Mode 0000005 32 Recorder Output Calibration 33 Recorder Output Limits Check 40 Adjusting the Light Source 42 MAINTENANCE 0 0200000205 44 Calibration Requirement 44 Hydraulic System 0 20 0000 eee 44 Reagents Supply 005 44 Changing Peristaltic Pump Tubing 46 Tubing Replacement 47 Y Strainer Cleaning 47 Cleaning Measurement Cell 47 Relay Test
