Auto Multimeter 6000Counts Intelligent Graphical Oscilloscope With Analog Graph Multi-function Resistance Frequency Diode Tester Features: 1. Multimeter: 200Msps high-speed sampling, 40MHz analog bandwidth, 6000-code digital multimeter. Overload protection 500mA/10A double fuse, double protection instrument. 2. Three Kinds Of Waveforms: The rotary knob converts the visual wave, there are three waveform scanning modes such as automatic/normal/single, the data waveform hold function during the measurement, can store 100 sets of data, 50 waveforms, and can set parameters independently during waveform measurement, such as Time base, waveform sweep mode, etc. 3. Anti-Interference: True RMS, measuring the RMS value of the waveform, without considering the waveform parameters and distortion, relative value measurement, effectively eliminating lead resistance, distributed capacitance or interference signals. 4. Multi-Function: The functions include DC/AC voltage/current, resistance, capacitance, frequency, temperature, diode/on-off test, triode. Automatic/manual range switching, and the measurement data and historical data are displayed on the same screen. 5. Automatic Shutdown: 15 minutes of no operation automatic shutdown function; bright backlight, clear display, panel calibration, memory calibration coefficient without potentiometer adjustment, higher reliability Specification: Material: plastic shell Size: about 160x83x32mm/6.29x3.27x1.26inch Display: 240x160 dot matrix graphics Observation area: 60mm x 40mm Input resistance: 10M Battery: 3xAA (not included) Auto Power Off: 15 minutes or disabled Operating altitude: 0~2000m Use time: more than 8 hours Storage capacity: 100 DMM data, 50 OSC waveform records Use environment: 0+40;
