Multimeter MF500 high-precision mechanical pointer meter inner magnetic outer magnetic 2500V. Fully automatic high precision AC DC voltage and current resistance measurement tool, a smart digital multimeter born for mobile phone repair. The MF500 series multimeter is a portable rectifier system with high sensitivity and multiple limits. It can measure AC and DC current, AC and DC voltage, DC resistance and audio level separately. It is suitable for radio, telecommunications and electrician institutions as general measurement. Features: The MF500 multimeter shell is made of phenolic compression molding powder, which has good mechanical strength and electrical insulation performance. The instrument is equipped with a sealing device to reduce the external dust and harmful gas from eroding the inside of the instrument. The dial of the instrument is wide, and the end of the pointer is knife-shaped, so it can clearly indicate the measured value. The battery box is located on the back of the meter and isolated from the inside of the meter, so it is convenient to replace the battery. The volume of the instrument: 178X 173X84 mm; SPECIFICATIONS: DC Voltage: 2.5 / 10/50/250/500 V / 2500 V AC Voltage: 10/50/250/2500 V Current DC: 0.5mA / 1mA / 10mA / 100mA / 500mA Resistance: R2K / R20K / R200K / 2M / 20M Dimensions: 178 * 138 * 84mm Weight: about1450g Power supply: 1.5V C battery 1 + 9V 6F22 battery * 1 & # 65288; without battery 65289; Accessories: test leads, Manual weight: more than 1 kg. CHARACTERISTICS: MF500 multimeter is a high sensitivity, portable, rectifier-based instrument. The instrument has twenty-four ranges, respectively, can measure AC and DC voltage, DC current, resistance, and audio level. basic function: DCV ACV DCA etc. mirror feature scale for accurate reading Classic design magnetic internal board head Bakelite shell overload protection. Note: Products with electrical plugs are designed for use in the US. Outlets and voltage differ internationally and this product may require an adapter or converter for use in your destination. Please check compatibility before purchasing. This watch needs to be equipped with one laminated battery (9V) and one AA battery (1.5V). Since the performance of the battery will fail after the storage period, the product does not come with a battery. If necessary, the cost will be calculated separately.
