About Dropshipping:1.Accept Dropshipping, and we will DO NOT put any invoices, QR codes, promotions in the shipment, So Dont worry, Just buy it, we will do anything well for you .2.We are guarantee each device be tested rigorous before shipped out, SO all products can guarantee 100% high quty before sent out.Thank you very much!!!Features and specifications:DSO FNIRSI PRO is a full function, high utility, high performance and cost-effective oscilloscope for the maintenance industry and the R & D industry. The oscilloscope has a real-time sampling rate of up to 20MS/s and a 5MHz analog bandwidth. With complete triggering function (single, normal, automatic), both the periodic analog signal and the aperiodic digital signal can be used freely. Large time base scanning mode can monitor slow level changes. Equipped with high efficiency one button AUTO, the measured waveform can be displayed without complicated adjustment. Display the High Definition LCD screen equipped with 2.4 inch 320*240 resolution. Extremely convenient and fast waveform storage function, built-in 16MB storage space, the maximum storage of 0 waveform pictures. Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions. Built in 1200mAh rechargeable lithium battery can be continuously charged for 3 hours at one time. Day mode and night mode can be changed according to their own preferences.:1:Memory compreion technology, waveform refresh screen does not flicker2:Afterglow display technology3:2.4 inch color display screen4:5MHz analog bandwidth @ 20MS/s sampling rate5:Fast waveform storage6:Built-in 16M storage space, the maximum storage of 0 waveform pictures7:Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions8:High measurement voltage range, 1X can measure 0 ~ 40 V, 10X can measure 40 ~ 800V9:Up to 11 s measurement:VPP,Vmax,Vmin,Vavg,Vrms,Frequent,Duty+,Duty-,Time+,Time-,Time10:At any time, the waveform display (pause function) is frozen11:Equipped with high efficiency one button AUTO12:Complete triggering function (single, normal, automatic)13:Built in 1200mAh rechargeable lithium battery can be continuously charged for 3 hours at one time14:Day mode and night mode15:Ultra small volume, easy to carrySpecifications:1:Analog band width: 5MHz2:Maximum real time sampling rate: 20MS/s3:Vertical sensitivity: mV/div ~ 200 V/div4:Horizontal time base range: S/div ~ 2nS/div5:Maximum input voltage: 40 V (1X probe), 800 V (10X probe)6:Storage depth: 40KB7:Input resistance: 1M8:ADC precision: 8bits9:Coupling mode: AC/DC10:Trigger mode: Single, Normal, Automatic11:Trigger edge: Ascending/descending edge12:External trigger voltage 0 – 40 V13:Display: 2.4 inch @ 320 * 24014:Power supply: 1200 mAh lithium battery15:Size: 107 x 70 x 24mm16:Weight: 1gPackage includes:1 x DSO FNIRSI PROoscilloscope host1 x Crocodile clip probe1 x Micro USB data line1 x User manual (English)1X gear measurement voltage in 0 ~ 40V, 10X gear measurement voltage in 40 ~ 800V, adjust to 1X gear need to probe and oscilloscope are set to 1X mode, adjust to 10X gear need to probe and oscilloscope are set to 10X mode, if the measurement of high-voltage signal, the probe switch toggled to the 10X position and the oscilloscope is in the 1X gear, will not the oscilloscope, but the measurement data abnormal
