[. . . ] Instruction Manual HI931300 HI 931301 Portable Microprocessor Logging pH Meters with Last Calibration Data Storage RANGE pH 0. 00 . +100. 0 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 more precise idea of its versatility in a wide range of applications. [. . . ] Press the CAL key to re-calibrate the value. CAL · If everything is satisfactory the secondary LCD will blink "50" expecting the second temperature measurement. Note: If a single point calibration is required, press the CAL key to leave the temperature calibration mode now. However, it is always better to proceed as follows for a two-point calibration. · Immerse the temperature probe in the container at 50°C (122°F). Place the probe as close as possible to the reference thermometer. CAL °C 50 °C (122 °F) · When "50" stops blinking, indicating that the probe has stabilized, press the CFM 21 key again to confirm the second calibration point. CFM · If the input is out of the slope range, "E2" as error message will appear on the secondary display. Press the CAL key to recalibrate the value. CAL If everything is satisfactory the temperature calibration is complete and the meter will resume the normal operational mode. 22 LOGGING FUNCTION (HI931300 only) LOGGING MODE In this mode data will be stored directly into memory for later retrival. Set the appropriate logging interval (see Operational Guide section on page 6). Press the ALT and the LOG keys simultaneously to enter the logging mode. The log number and page number will appear for a few seconds on the display to indicate the correct operational mode. ON/OFF LOG ALT CAL When the meter is in logging mode, "LOG" is displayed on the bottom left corner of the LCD with the time on the primary display and the logging interval on the secondary one. During logging, press the LOG key to show the total number of data that has been logged (sample number). TIME LOG INTV LOG To view measurements during logging press the RANGE key and the display will show the temperature. °C RANGE 23 To view the pH values press the RANGE key again. pH RANGE To return to the logging information press the LOG key. LOG After approximately 5 minutes the display will switch off but the logging function remains active. To reactivate the display press the ON/OFF key. ON/OFF Note: Once in the logging mode, the interval cannot be changed. Exit the logging mode first (pressing the ALT and the LOG keys) before setting the new interval. ON/OFF LOG ALT CAL TO STOP LOGGING To stop logging, press the ALT and LOG keys simultaneously. The display will show the lot and page number again for a few seconds. ON/OFF LOG ALT CAL The running lot number can be reset by simply removing and replacing the batteries. 24 DATA TRANSFER TO PC HI 931300 contains infrared emitting circuitry. Set the meter to the TIME mode and simply place your data-logger on a HI9200 Infrared Transmitter (ensuring that TIME the two infrared LEDs are placed on top of each other) and the memory can then be downloaded to your PC through the HI9200's RS232 port. During the data transfer the instrument displays the message "r 232". Using the HI9200 Infrared Transmitter, all recorded data can be fed to your Personal Computer for easy reproduction, storage or elaboration without the interference of cables or cords between the meter and the transmitter. Data transmission from the instrument to the PC is now much easier with new HI92000 Windows® compatible application software offered by Hanna Instruments. Windows® is registered Trademark of "Microsoft Co. " 25 HI92000 allows you to use the powerful means of most spread sheet programs (e. g. Simply open the file downloaded by HI92000 and it is possible to make any elaboration available with your software (e. g. User friendly, HI92000 offers a variety of features and has an on line help to support you throughout any situation. To install HI92000 you need a 3. 5" drive and a few minutes to follow the instructions conveniently printed on the disk label. FAULT FUNCTIONS Erroneous solution used for the offset calibration For pH calibration: Make sure the buffer solution used is pH 7 and replace if necessary For temperature calibration: Make sure the water is at 0°C/32°F Erroneous solution used for the offset calibration For pH calibration: Make sure the buffer solution used is pH 4 or 10. For temperature calibration: Make sure the hot water is at 50°C/122°F Low Battery Voltage Replace the batteries. LO BAT Excel© Copyright of "Microsoft Co. " Lotus 1-2-3© Copyright of "Lotus Co.
