[. . . ] Instruction Manual HI 98360 Autoranging & Logging Portable Waterproof Microprocessor EC/TDS/NaCl/°C Meter w w w. c o m Dear Customer, Thank you for choosing a Hanna Instruments product. Please read this instruction manual carefully before using the instrument. This manual will provide you with the necessary information for correct use of the instrument, as well as a precise idea of its versatility. [. . . ] The sleeve holes must be completely submerged. Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve. For zero calibration, just leave the dry probe in air. The indications "STD" and "CAL" are displayed. The upper LCD shows the uncalibrated EC reading. The stability indicator " " blinks. Select the desired value with the and keys, if necessary. When the " " symbol stops blinking, the reading is stable. The "CFM" indication starts blinking on the LCD asking for confirmation. Press ALT+CFM to confirm the calibration. If everything is satisfactory, the meter displays the "Stor Good" message and returns to measurement mode. Notes: · If the uncalibrated reading is too far from the expected value or the temperature value is out of 0 ­ 60°C range, calibration is not recognized. The "CFM" indication does not appear; the " " and "STD" symbols blink to signal wrong or contaminated calibration solution. If the temperature value is out of 0 ­ 60°C range, the "°C" tag will also be displayed blinking on the LCD. · For best results choose a calibration value close to the sample to test. · In order to minimize the EMC interferences, use plastic beakers. · The meter uses 1. 90%/°C compensation factor during calibration. If the setup item "tc" has been set to a different value, when exiting the calibration mode the value displayed on the upper LCD could be different from the nominal buffer value. · It is possible to set the cell constant value directly without following the calibration procedure. To set the cell constant enter the setup mode and select "CEL" (see SETUP for details). 12 NaCl CALIBRATION Calibration is 1-point at 100. 0% NaCl. Use the HI7037 calibration solution (sea water solution) as a 100% NaCl standard solution. · To enter NaCl calibration select the NaCl range and press CAL.

Operation of this instrument in residential areas could cause unacceptable interferences to radio and TV equipment, requiring the operator to follow all necessary steps to correct interferences. The metal bands of the probe are sensitive to electrostatic discharges. [. . . ]
