Set the time, temperature, voltage, three functions in one<br>2. manual error correction function with a temperature setting range -5 ~ 5<br>3. With backup battery, power-down time to continue to go<br>Electrical Characteristics:<br>1. Input voltage 5 ~ 30V. Note that to use a voltmeter function, the input voltage is at least more than 7V<br>2. voltmeter range 7 ~ 30V, error ± 0.1V, the measured voltage is the input voltage. (Can also function as a wide range of uses voltmeter, power is more convenient, such as a pen so you can remember this power, and do not exceed the maximum voltage of 30V)<br>3. Temperature measurement range -50 to 130 degrees, the temperature resolution of up to 0.1 degrees<br>4.
