[. . . ] Instruction Manual HI 9835 Autoranging Portable Waterproof Microprocessor EC/TDS/NaCl/°C Meter Manufacturers since 1978 This Instrument is in Compliance with the CE Directives Dear Customer, Thank you for choosing a Hanna product. Please read this instruction manual carefully before using the instrument. This manual will provide you with the necessary information for a correct use of the instrument, as well as a precise idea of its versatility. If you need additional technical information, do not hesitate to e-mail us at tech@hannainst. com. [. . . ] The indications "BUF" 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 "CON" 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 I If the uncalibrated reading is too far from the expected value, calibration is not recognized. The "CON" indication does not appear; the " " and "BUF" symbols blink to signal wrong or contaminated calibration solution. II For best results choose an EC buffer value close to the sample to be measured. 9 TEMPERATURE COMPENSATION Three options of compensating temperature are available: Automatic (Atc): The probe has a built-in temperature sensor; the value of the temperature is used to automatically compensate the EC/ TDS reading using 25 C as reference temperature. Manual (Mtc): The temperature value, shown on the lower LCD, can be manually set by the user with the up and down arrow keys. The " C" symbol blinks when this option is active. No Compensation (notc): The temperature reading shown on the lower LCD is not taken into account. The reading displayed on the upper LCD is the actual EC or TDS value. The " C" and "%TC" symbols blink when this option is active. To select the desired option press the ATC key until the option is briefly displayed on the LCD. Note: The default compensation mode is ATC. If temperature compensation is active, measurements are compensated using a default temperature coefficient of 1. 90 %/ C. It is possible to select a different temperature coefficient (TC) in the 0. 00 to 6. 00 %/ C range by entering the setup mode and selecting the "tc" item (see SETUP for details). The current temperature coefficient can be quickly viewed pressing ALT+TC. The value is briefly displayed on the lower LCD. 8 III IV V In order to minimize any EMC interference, use plastic beakers. [. . . ] After cleaning the probe, recalibrate the instrument. 14 15 ACCESSORIES CONDUCTIVITY BUFFER SOLUTIONS HI 70030P HI 7030L HI 7030M HI 70031P HI 7031L HI 7031M HI 70033P HI 7033L HI 7033M HI 7034L HI 7034M HI 7035L HI 7035M HI 70039P HI 7039L HI 7039M HI 7037L 12880 µS/cm (µmho/cm), 20mL sachets (25 pcs. ) 12880 µS/cm (µmho/cm), 460mL bottle 12880 µS/cm (µmho/cm), 230mL bottle 1413 µS/cm (µmho/cm), 20mL sachets (25 pcs. ) 1413 µS/cm (µmho/cm), 460mL bottle 1413 µS/cm (µmho/cm), 230mL bottle 84 µS/cm (µmho/cm), 20mL sachets (25 pcs. ) 84 µS/cm (µmho/cm), 460 mL bottle 84 µS/cm (µmho/cm), 230 mL bottle 80000 µS/cm (µmho/cm), 460mL bottle 80000 µS/cm (µmho/cm), 230mL bottle 111800 µS/cm (µmho/cm), 460mL bottle 111800 µS/cm (µmho/cm), 230mL bottle 5000 µS/cm (µmho/cm), 20mL sachets (25 pcs. ) 5000 µS/cm (µmho/cm), 460mL bottle 5000 µS/cm (µmho/cm), 230mL bottle 100% NaCl sea water standard solution, 460mL OTHER ACCESSORIES HI 76309 HI 76310 HI 710005 HI 710006 HI 710012 HI 710013 HI 710014 HI 740027 HI 740036 HI 740034 HI 76405 stainless steel 4-ring conductivity/TDS probe with temperature sensor and 1m (3. 3') cable. platinum 4-ring conductivity/TDS probe with temperature sensor and 1m (3. 3') cable. 12VDC voltage adapter (US plug) 12VDC voltage adapter (European plug) 12VDC voltage adapter (UK plug) 12VDC voltage adapter (S.
