KJ610x Series Safety rules and precautions · Please read the manual carefully before using the instrument. · Please check the instrument hasn’t any damage with good meter pen insulating layer before using the instrument. · Every measuring operation is under direction of drawing, on which each number indicate one operation, it may standard your measuring action and impel you to form a good operation habit. · Before opening the battery cover, please pull off the meter pen first; after closing the battery cover, you should screw on the bolts firmly and then start to measure; if not, electric shock may occur. · The input voltage and current cannot exceed the range stipulation. · It is regarded to be dangerous voltage if DC exceeds 60V or AC exceeds 42V, please operate the device carefully and cautiously to avoid electric shock. · The common mode voltage between COM (public end of meter measurement) and the voltage to earth cannot exceed 1000V. · The fuse inside the instrument should be replaced only with these fuses having same specification. · If the LCD displays the battery icon, it indicates the battery voltage is insufficient and it should be replaced with new one to ensure the normal working of the instrument. · If the instrument shall be not used for a long period, please take out the battery to avoid the battery leakage to damage the device. · Please keep the instrument in a dry place and away from damp. · Do not dismantle, alter or rebuild the instrument by yourself. Overview Features of KJ61 series digital multimeter: ★ The casing and protective sheath are made by antiflaming engineering plastic and equipped with magnetic hook. ★Sound alarm will be automatically activated if the meter pen is inserted wrongly; the corresponding relation is the same to mechanical baffle. ★NCV (non-contact voltage test) is attached for free.
