[. . . ] This instrument is in compliance with the directives. FUNCTIONAL DESCRIPTION SPECIFICATIONS PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer or the nearest Hanna Office. Note: Save all packing materials until you are sure that the instrument functions correctly. [. . . ] The meter is also provided with low battery detection and BEPS (Battery Error Preventing System), which turns the unit off when battery is discharged avoiding erroneous readings caused by low battery level. HI 9040 features include a dual-level LCD for simultaneously displaying of maximum and minimum measured temperatures, °C/°F selection button and HOLD function. Each meter is supplied complete with a HI 765BL thermistor probe, a 9V battery and instruction manual.

Unwrap the supplied 9V battery, connect it to the clip and reattach the cover. Connect the temperature probe to the connector on the top of the meter. The thermometer will carry out a self diagnostic test routine, the LCD will show all segments for a few seconds (or as long as ON/OFF is held), followed by the percentage indication of the remaining battery life. If a temperature probe is plugged in, the meter displays the measured temperature. If no probe is plugged in, or if reading is over-range, the display shows flashing dashes. If a measurement is slightly over the range of the meter specifications, the display flashes the closest full-scale value. To switch the thermometer OFF, press the ON/OFF key. Note: When reading goes over-range, the Hi and Lo values display dashes until cleared. FACTORY RECALIBRATION All Hanna thermometers have been accurately pre-calibrated at the factory. It is recommended to have all thermometers recalibrated at least once a year. For an accurate annual recalibration, contact your nearest Hanna Service Center. Hanna Accuracy Test Plugs provide a quick and easy way to test the meter's accuracy by simply connecting these Test Plugs to the probe connector of the meter. If the reading differs by more than ±0. 4°C (±0. 8°F) from the Test Plug value, the meter is due for recalibration. Choose the Test Plug closest to your measurement range to best suit your needs: HI 765-18C Calibration key, ­18. 0°C HI 765000C Calibration key, 0. 0°C HI 765070C Calibration key, 70. 0°C HI 765-004F Calibration key, ­0. 4°F HI 765032F Calibration key, 32. 0°F HI 765158F Calibration key, 158. 0°F TEMPERATURE PROBES & ACCESSORIES Hanna offers a wide range of probes to meet your needs with air, liquid, penetration and surface measurements. All Hanna temperature probes are pre-calibrated at the factory and ready-to-use. [. . . ] To avoid damage or burns, do not perform any measurement in microwave ovens.
