2.5Msps high-speed sampling, 1MHz analog bandwidth, 4000 count digital multimeter. One-click visual wave, there are three waveform scanning modes: automatic/conventional/single. Save function for data and waveform in the measurement;a total of 100 sets of data and 10 waveform can be saved. When measuring waveforms, you can set parameters independently, such as: time base, amplitude, waveform scanning mode, etc. REL, effectively the lead resistance, distributed capacitance and interference signal. Multimeter functions include DC/AC voltage/current, resistance, capacitance, frequency, duty cycle,diode continuity test. Automatic/manual switching for measuring range and display of measurement data and historic data on the same screen. Overload protection 10A double protective tube, dual protection of the inst ent. Automatic shutdown in case of no operations for 15 minutes: bright backlight and clear display. Adopt 2.4 inch color screen display, the display effect is clear. Higher reliability: no adjustment of potentiometer is required for panel calibration and internal storage calibration. Automatic measurement function: -p, Vavg, Vrms, HZ DC Voltage: 400mV-600V DC Current: 4A-10A Resistance: 400.0-40.00M Frequency: 5Hz-5MHz Diode test: Voltage is about 1.5 V AC Voltage: 400mV-600V AC Current: 4A-10A Capacitance: 51.2nF-100uF Duty cycle: 0%-100% Continuity test: Resistance Less than 50,beep Display: 240x320 Color screen Backlight: Constantly on Battery: AA batteries x 3(Not included) Working current: About 65mA usage time: More than 10 hours Use: 0-+40;Less than 75%RH Dimensions:77 mmx157 mmx25.5mm Observation area:49.0 mm x 36.7 mm Name:Oscilloscope multimeter Colour:As Shown Material:Plastic Package Contents: 1 x Oscilloscope multimeter 1 pair x test leads Only 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. The measurement allowed error is +/- 1-3cm.
