Multifunctional Electronic Thermometer LCD Digital Temperature Detector ℉ ℃ External Sensor Thermometer for Kitchen Baking. Fahrenheit Celsius temperature conversion; maximum temperature, minimum memory function; temperature data hold function; 5 seconds high and low temperature alarm settings; Technical parameters: Measuring range: -50 ℃ - + 300 ℃ (-58 ℉ - + 572 ℉); resolution: temperature (-19.9 ℃ - 199.9 ℃) 0.1 ℃, other 1 ℃; accuracy: ± 1 ℃ (± 1.8 ℉), other range: 20 ℃ - + 80 ℃ power : AAA alkaline batteries a 1.5v NOT include. use of the environment: humidity 5% - 85% RH, temperature: 0 ℃ - 50 ℃ operating instructions: power (ON / OFF) to display the full stroke, then enter the measurement mode. alarm settings (SET): the SET key to enter the alarm setting mode. Cycle Adjustment (ADJ) and confirmation (OK); enter the temperature setting mode mode (temperature value is only expressed in degrees Celsius C) "Hi" and a high temperature alarm temperature starts flashing, indicating the start of high temperature alarm temperature settings. the ADJ button click can add a high-temperature alarm temperature, two seconds automatic functions plus a return to the high temperature than low temperature alarm temperature 1 ℃ temperature alarm when the temperature regulated above 300 ℃, the upward turn plus with "OK" to confirm. Enter the low temperature alarm settings. "Lo" temperature and low temperature alarm starts flashing. ADJ can add a low-temperature alarm temperature, often by two seconds with an automatic plus one function, when transferred to the high temperature alarm temperature alarm on low temperature value, the value returned to -50 ℃, and "OK" to confirm. After the alarm setting is completed, "Hi" and "Lo" disappeared, "AL" display indicates incoming alarm measurement mode. Cancel alarm (AC): P the "AC" key, measuring from the alarm mode into the measurement mode, "AL" disappear. note: For best results, the probe into the measurement object at least 10mm.
