GENERAL DESCRIPTION HI 8757 and HI 8758 are Hanna microprocessor-based, Ktype thermocouple thermometers specially dedicated to education. These meters perform measurements either in °C (HI 8757) or °F (HI 8758) in a wide range of temperature; readings are linearized for increased accuracy, and resolution is automatically switched from 0. 1° to 1° for temperatures above 200°C (400°F). These thermometers are also provided with battery level indication at start-up, and with the BEPS feature (Battery Error Prevention System), which automatically switches the instrument off when the battery is discharged to avoid erroneous readings due to low battery level. Each meter comes complete with a 9V battery and instruction manual.

Unwrap the supplied 9V battery, connect it to the battery clip and reattach the cover. Connect the temperature probe to the connector on the top of the meter. To switch ON, turn the rotary knob to the ºC or ºF position (depending on the model). The meter displays the percentage indication of the remaining battery life for a few seconds, and then enters measurement mode. If a temperature probe is plugged in, the meter displays the measured temperature either in °C (HI 8757) or °F (HI 8758), automatically switching to the resolution suitable to the temperature range; i. e. 0. 1° up to 199. 9°C (399. 9°F), or 1° above. [. . . ] Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance. To avoid electrical shock, do not use these instruments when voltage at the measurement surface exceeds 24VAC or 60VDC. To avoid damage or burns, do not perform any measurement in microwave ovens. FACTORY RECALIBRATION All Hanna thermometers have been accurately pre-calibrated at the factory. [. . . ]
