Digital Multimeter for Household Outlets, Fuses, Vehicle Battery, Charging System, Automotive Circuits Trouble Shoot The basic electronic meter around household or in electronic industry. Meet your demands with durable quality and a variety of usage include checking whether the battery, fuse and circuit is well functioned, for vehicle maintenance and any other function a multimeter can do, also support transistor , Diode test and hFE test. The rubber case kickstand and overload protection on all range with durable ABS material ensure it is safe to use. Measurement ranges: DC Voltage: 200mV/2V/20V/200V +- 0.5%, 600V +- 0.8% AC Voltage: 200V/600V +- 1.2% DC Current: 200A/2mA/20mA +- 1%, 200mA +- 1.5%, 10A +- 3% Resistance: 200Ω/2KΩ/20KΩ/200KΩ/2MΩ +- 0.8% Add-on features for optimum user experience Comes with Audible continuity test buzzer to ensure all electrical component are still in working condition. Data hold function makes you never miss track of readings. Built-in Over-load protection to indicated issues and keep you from harm. A low-power reminder, you are never going to be out of battery suddenly. Specification: Max Display: LCD3 ½ digits (1999 count) 0.6” High Polarity: Automatic, indicated minus, assumed plus. Measure method: double integral A/D switch implement Fuse Protection: F-200mA/250V. Sampling speed: 2 times per second Over-load indication: “1” is displayed Polarity Indication: "-" displayed for negative polarity. Operating Environment: 0°C~40°C, at <80% RH Power: 9V NEDA 1604 or 6F22 Static electricity: about 4mA Notice: - Don’t change the inner circuit to avoid damaging the ammeter. - Don’t connect it to the voltage over 1000VDC or 750VAC. - Don’t connect the error measure range. Do nott use the ammeter if the back cover is wrong .
