Professional Shock Digital Multimeter is a kind of convenient operation, accurate readings, complete function, small size, easy to carry and use battery as power handheld large screen LCD multimeter, for three and a half digital multimeter, the table can be used to measure dc voltage/current, ac voltage/current, resistance, capacitance testing, diode test, transistor HFE measurement and on-off circuit, etc. For engineering design, laboratory, production test, factory affairs, field operation and industrial maintenance use. The function of fault gear, as well as A superior performance over range protection against the burning protection (machine with insurance tube) automatic shutdown function better protect battery COMS integrated circuit, the principle of double integral A/D conversion zero self-adjustment, automatic polarity selection range scale. 1 - on-off test buzzer sound and light emitting diode instructions.
High quality parameter index of CMOS integrated circuits, double integral A/D conversion, automatic zero, automatic choice of polarity, super range scale LCD screen using 70 * 40 mm large screen, high contrast words up to 25 mm.According to the observation position needs, are free to change the Angle of about 70 multimeter display Angle, in order to obtain the best effect of observation With functions of automatic shutdown, boot after about 15 minutes will automatically cut off power supply, in order to prevent the instrument power forget close repeat power switch operation, after operation can continue to boot. New optimization design of high reliable range rotary switch structure/function.Adopting 32 gear.More effectively and avoid the wrong operation The performance Details: the function and characteristics of the range accuracy Dc voltage 200 mv - 1000 v±(0.5% + 1) Ac voltage 200 mv - 750 v ±( 0.8% + 3) Dc current 20 ma-20a±(0.8%+ 1) Ac current 20mA-20A±(1%+ 3) Resistance 200?-2000M?±(2.5%+ 3) Capacitance 2 nf - 200 mu F Crystal diode test is yes Diode testing is yes Conduction buzzer is yes Automatic shutdown is yes 6 making power 9 v,6F22
