[. . . ] Instruction Manual HI 98140 - HI 98150 Portable Waterproof Microprocessor Logging GLP pH / ORP Meters www. hannainst. com These Instruments are in Compliance with the CE Directives 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 all the necessary information for the correct use of the instrument, as well as a precise idea of its versatility in a wide range of applications. These instruments are in compliance with the TABLE OF CONTENTS PRELIMINARY EXAMINATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . [. . . ] The meter will display "1900 mV" on the lower LCD with the "BUF 3" indication. When the "CFM" symbol blinks, the reading is stable. Press ALT and CFM to confirm the third value. Calibration is now complete, the instrument returns to normal operational mode. Note: "WRONG" message notifies the user if the selected value is wrong. TEMPERATURE CALIBRATION PROCEDURE (for technical personnel only) A two point calibration at 0. 0, 50. 0°C has to be performed in order to store the new calibration data in memory. Immerse the pH electrode with the built-in temperature sensor in the 0°C temperature bath. Press ALT and CALT to enter temperature calibration mode. The meter will display "0. 0 °C" on the lower LCD with the "BUF 1" and "CAL" indication. When the reading is stable the "CFM" symbol starts to blink. LCD will then display 50. 0°C on the lower LCD with the "BUF 2" indication. Immerse the pH electrode with the built-in temperature sensor in the 50°C temperature bath. When the reading is stable the "CFM" symbol starts to blink. Press ALT and CFM to confirm and return to normal operational mode. 16 LOGGING FUNCTION To store the current reading in memory press the LOG key while in measurement mode. The LCD will display "Stor" along with the "LOG" indication and the sample number for a few seconds. By pressing the LOG key a complete set of information is memorized: date, time, pH and mV (HI98150 only) readings, temperature reading and also a message on the meter status. Up to 500 samples can be stored into memory. When the memory is full and the LOG key is pressed, the sample will not be stored and the LCD will display "FULL". In this case it is necessary to delete all the memory to proceed. TO VIEW LOGGED DATA To retrieve the memorized information press ALT and RCL. The meter displays the date (upper LCD) and the number (lower LCD) of the last logged sample. The "ZERO" indication will be displayed if no samples are stored in memory. · Select the desired sample number with the arrow keys. Pressing the key while the last sample is displayed causes the meter to go to the first sample. · Press RANGE to view remaining data of the selected sample. After the date information, the remaining data will be displayed in the following order: 17 - year - time - pH reading "----" means reading out of range or no probe was connected. "OrP" means that an ORP electrode was connected.
