Safety... - Page 2 一、General General General VICTOR 81A/B is a steady performance, high security 3 1/2 digital multimeter. It uses LCD with 18.9mm high figure to make the reading clear. The digital multimeter has the function of measuring ACV, DCV, ACA, DCA, Resistance, Celsius & Fahrenheit Temperature, Diode, Continuity. The instrument also has the features of Unit Symbol Display, Auto/Manual Range Selection, Auto Power Offer and Alarm Function.
- Page 3 三、Safety Safety Note Safety Note Note The instrument is designed according to IEC1010 standard (safety standard issued by International Electro technical Committee). Please read the following before operation. Caution to avoid the electric shock when measuring voltage higher than 36V DC, 25AC, current higher than 10mA, AC power line with inductance load and AC power line during the power fluctuation.
- Page 4 output socket or lead clamp with ground potential. Usually use the dry cloth, rubber overshoes, rubber cushion and other insulated materials to keep the body isolated with the ground. Do not store and use the instrument in high humility, high temperature, combustible, explosive and strong magnetic places.
- Page 5 Do not try to modify the inner circuit at will to avoid damaging the instrument and endangering the safety of the users. 15． Safety Symbol Description： Warning! Warning! Warning! High Voltage Voltage! ! ! High High Voltage Dangerous! Dangerous! Dangerous! DCA &...
