Standard features include: • Interchangeable probes FUNCTIONAL DESCRIPTION AND SPECIFICATIONS FOR HI 9056 • Clear Liquid Crystal Display • Two year Warranty • Possibility of switching between the Centigrade and the Fahrenheit scale (for HI 9057 only) • HOLD function that freezes the reading on the display (for HI 9057 only) • HI-LO memory recall function (for HI 9057 only) • Low battery detection. All these functions are easily accessible through the keypad.
FUNCTIONAL DESCRIPTION AND SPECIFICATIONS OF HI 9057 OPERATIONAL GUIDE INITIAL PREPARATION Remove the battery cover on the rear of your thermometer, unwrap the battery and connect it to the clip. Insert the battery into the compartment and replace the cover. To switch on, press ON/OFF on the front of the unit. 1. Liquid Crystal Display 2. ON/OFF Key 3. Reading Memory/Hold Key 4. Thermocouple Type Selection Key (K or J or T) 5. Minimum Temperature Recalling Key 6. Maximum Temperature Recalling Key 7.
To change the scale, press °C/°F once. °C °F °F MEASUREMENT RESOLUTION When switched on, HI 9056 °C and HI 9057 default to a 0.1 digit resolution (see specifications). These instruments automatically change the resolution to 1 degree when the measured temperature is higher than 999.9°C. In HI 9056, when the temperature is lower than 999.9°C it is possible to change the resolution by pressing the 0.1/1 key. HOLD MODE (HI 9057 only) The reading hold function is activated by the HOLD key.
The memory value will be overridden each time the memory & hold function is activated. A blinking "MEM" on display indicates the operating mode. Press and hold MR to recall previously stored temperature reading. In this mode of operation, the display indicator "MEM" is shown. TEMPERATURE DIFFERENCE (HI 9056 only) The difference between the temperature measured by the two probes can be displayed by simply pressing ∆T. A "∆" will appear on the left-hand of the display to indicate this function.
CALIBRATION All Hanna Instruments thermometers have been accurately pre-calibrated at the factory. It is generally recommended to have all thermometers recalibrated at least once a year. For an accurate annual recalibration, contact your nearest Hanna Service Center. BATTERY REPLACEMENT SHOCKPROOF RUBBER BOOTS These rubber boots are specially made to prolong the life of your instruments and to prevent damage due to accidental falls.
