GENERAL DESCRIPTION HI 9040 is a hand-held microprocessor-based thermometer which allows fast and accurate temperature measurements, using a calibrated thermistor probe. The temperature probe is linearized by the microprocessor. 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. To switch ON, press the ON/OFF key on the front 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. The thermometer then enters normal measurement mode. 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. [. . . ] To avoid damage or burns, do not perform any measurement in microwave ovens. HOLD MODE The HOLD function is activated by pressing the HOLD key. The measured temperature is held on the display until HOLD is pressed again. The "H" tag blinks on the display to indicate the HOLD mode. Note: Although the display is frozen, internally the meter continues measuring and updating Hi and Lo values. Remove the cover on the meter's back by applying pressure in the indicated direction.
