FNIRSI 2C23T - Digital Multimeter, Dual Channel Oscilloscope, 3in1 Generator LCD 2.8" 10 MHz AC Main features: LCD : 2.8", HD , 320×240 Adjustable display brightness Battery capacity: 3000 mAh Standby mode: max. 6 hours Charging port: USB-C Charging input parameters: 5V/1A Menu language: English, Russian, Portuguese, German, Japanese Dimensions: 167×89×35 mm FNIRSI 2C23T is a versatile device designed for professional and amateur engineers, electronics engineers, and students . This compact and extremely functional device combines multimeter, oscilloscope and signal generator. It allows you to perform a wide range of measurements and tests na one device. FNIRSI 2C23T is equipped with a large color display diagonal 2.8" and HD 320×240p resolution. Its strong i durable construct uses high-quality ABS plastic, which is supplemented with silicone protection on the corners. All this makes it ideal for working not only in laboratories and workshop, but also for field workers. FNIRSI 2C23T is powered by an integrated battery with a capacity of 3000mAh. Charged za via the USB-C connector. The charged device works up to 6 hours in standby mode. It has a storage function with easy data export to computer za using the USB cable. Signal generator generates various types of signals for circuit testing, which is necessary for diagnosis and debugging electronic devices. The integrated DDS function signal generator can generate 7 types of function signals with a maximum output of 2 MHz for all signals and a step of 1 Hz . Output frequency, amplitude and duty cycle are adjustable. Multimeter exactly measures voltage, current, resistance and other electrical parameters. Measurement is easy thanks to the aautomatic measuring range. Oscilloscope is a tool for visualization and analysis of electric signals in real time. It enables to identify problems in electronic circuits and test components. The oscilloscope uses hardware architecture: FPGA+MCU+ADC z sampling rate 50MS/s Analog bandwidth 10MHz built-in high voltage protection module maximum support for peak voltage measurement ±400V Technical specification: Oscilloscope: Channel: two-channel Sampling rate: 50 M Analog bandwidth: 10M (regardless of two 10M channels) Memory depth: 32 kb Impedance: 1MΩ Time Base Range: 50ns-10s Vertical sensitivity: 20 mV/div-10V/div (X1) Maximum measured voltage：±400V Starting mode: automatic/nor­mal/simple Trigger type: rising slope, descending slope Display Mode: YT/Scroll Connection method: AC/DC Saving Curve Screenshot: Yes Exporting curve images：Yes Generator: Channel: one channel Frequency: 1Hz-2MHz Amplitude: 0.1-3.3V Multimeter: Voltage DC: 9,999 V~999,9 V Voltage AC: 9,999 V~750,0 V Constant Current: 9999μA~9.999A Current AC: 9999μA~9,999A Resistance: 999,9Ω~99,99MΩ Capacity: 9,999 nF~99,99 mF Temperature:(-55~1300℃)/(-67~2372℉) Diode: Yes Continuity test: yes LIVE detection: yes
