Feature: 1. 2.5Msps high-speed sampling, 1MHz analog bandwidth (only ACV oscilloscope), 4000 code digital multimeter. One-key oscilloscope, there are three waveform scanning modes: auto/normal/single.2. Data waveform retention function during measurement can 100 groups of data and 10 waveforms. The parameters can be set independently during waveform measurement, such as time base, amplitude, waveform scan mode, etc.3. Relative value measurement can effectively eliminate lead resistance, distributed capacitance or interference signals. Multimeter functions include DC/AC voltage/current, resistance, capacitance, frequency, duty , diode/continuity test.4. Automatic/manual range switching, real-time data and stored data are displayed on the same screen. Overload protection 500mA/10A double fuse, double protection meter.5. Automatic sleep function without operation for 15 minutes. Adopt 2.4 inch color screen display, the display effect is clear. Panel calibration, memory calibration coefficients do not need potentiometer adjustment, higher reliability.Specification:Instrument characteristics and technical parameters:Display: 240X320 color screenObservation area: 49.0mm x 36.72mm/1.93x1.45inBacklight: Always onInput resistance: about 10MBattery: 3 X AA batteries (not included)Automatic sleep: 15 minutes or disabledStatic working current: about 65mASleep current: about 35uAContinuous use time: more than 10 hours, (battery capacity/about 65mAh)Storage capacity: 100 data, 10 OSC waveform recordsUse environment: 0 - +40 degrees Celsius; Less than 75%RHStorage conditions -10 - +60 degrees Celsius; Less than 90%RHDimensions: 160x83x32mm/6.3x3.27x1.26insize: 160x83x32mmMaterial: ABScolour: blackPackage Contents:1 x 2 x Test Leads kit1 x English ManualOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
