TABLE OF CONTENTS Warranty ...................................................................................
PRINCIPLE OF OPERATION FUNCTIONAL DESCRIPTION HI 93124 has been designed to perform turbidity measurements according to the EBC (European Brewery Convention) Standard. The instrument functions by passing a beam of infrared light through a cuvette containing the sample being measured. The light source is a High Emission Infrared LED with a wavelength peaking at 890 nm, ensuring that the interference caused by colored samples is minimum.
SPECIFICATIONS Range 0 to 10.00 EBC 10 to 250 EBC Resolution Accuracy 0.01 EBC or 1 EBC ±0.20 EBC ±3% of reading (0.00 to 10.00 EBC) ±1 EBC ±5% of reading (outside) Typical EMC Deviation ±1% F.S. Light Source Infrared LED @890 nm Light Source Life Life of the instrument Light Detector Silicon Photocell Power Source 4 x 1.5V AA alkaline batteries Battery Life 60 hours or 900 measurements Auto-off OPERATIONAL GUIDE The instrument is supplied complete with batteries.
• Press the READ key and the LCD will display a blinking “SIP” (Sampling In Progress). The measured value will appear after approximately 25 seconds. VIEWING LOGGED DATA • Press ALT+VIEW keys: the last sample will be displayed. • Press the “right arrow” key to scroll among turbidity value, date and time of the sample. • Press the “up/down arrow” keys to view next sample and use the “right arrow” to scroll the date and time.
CALIBRATION If repeated measurements differ more than an acceptable value, check if the meter calibration status by measuring a standard solution. Anyway, it is recommended to perform a monthly calibration of the meter, or more frequently for greatest accuracy. To check the date of last calibration, simply press the GLP/CAL key. Press again to toggle between date and time. CALIBRATION PROCEDURE • Turn the meter on and wait for the display to show dashes “----”.
TIPS FOR ACCURATE OPERATION LCD ERROR CODES The instructions listed below should be carefully followed during testing and during calibration. • All glassware that comes into contact with standards should be maintained clean. Wash with HI93703-50 cleaning solution and rinse with HI 93124-0 or turbidity free water. • For consistent readings, it is recommended to perform measurement immediately after collecting sample. • To obtain a representative sample, gently mix the liquid before samples are taken.
BATTERY REPLACEMENT CE DECLARATION OF CONFORMITY In order to minimize the battery consumption, the meter is equipped with an autoshut off function which switches the meter off after 5 minutes of non-use. The meter is powered by 4 alkaline batteries (1.5V AA), which are constantly monitored by the meter to ensure reliable readings. A "LO BAT" indication will appear on the display when the batteries become weak and require replacement; the instrument can perform only 50 more measurements.
