The range of this signal generator is 0-10V/0-22mA, which provides a new generation of digital signal generators with all-digital encoder adjustment settings. Compared with traditional resistance adjustment, it avoids the temperature and time resistance offset band. To solve the drift problem, the digital adjustment is more accurate and convenient, and the setting functions are more abundant.      4 power supply modes: external DC15-30V/USB-5V/built-in lithium battery /; emergency AC transformer power supply (AC12-24V); One-key switching of voltage and current adjustment, independent wiring, and simultaneous output      Current output 2, 3, 4-wire system, passive and active are fully compatible; The output has short-circuit protection, the power supply has no polarity access, and has DC bridge isolation protection; Output range: 0-3.3/5/10/2-10/1-5V... 0-20/0-22/4-20mA...      Multiple display modes: voltage and current/100.0% percentage/50.0HZ...; Coarse and fine-tuning dual mode, the number of adjustment circles can be set; Lithium battery charge and discharge overcurrent protection, automatic charge management, power indicator      The encoder knob is 360-degree infinitely adjustable, stable and durable, unlike the adjustable potentiometer, which is easily affected by temperature and humidity, and the carbon brush becomes thinner and thinner after prolonged use, and the resistance value changes            4-digit high-brightness digital tube, two-digit decimal point high-precision adjustment, and the output can be calibrated      High-grade aluminum alloy knobs, electroplated buttons, beautiful shell, comfortable to hold      Pluggable terminals, easy to install and carry      Working voltage: DC24V (allowable range: DC12V ~ 30V).      Working current: power 1W (not charging)/5W (charging);      maximum charging current 0.8A;      External microUSB- 5V current 0.2A(not charging)/1A (charging);      Voltage output 0-10V adjustable, accuracy 0.01V can be calibrated, maximum current 100mA, short circuit protection;      Current output 0-22mA adjustable accuracy 0.01mA can be calibrated;      Current sampling resistance 10-500 ohms, can be short-circuited;      The digital tube displays 4 digits and two decimal places;      20 additions and subtractions per turn of the encoder knob;      Working temperature: -0°C~50°C      Working humidity: 0~95%RH      Storage temperature: -40°C~85°C      DIY Supplies:ELECTRICAL      Supplies:ElectricalDisplay      color:White      Material:plastic            Package Contents:      1 x signal generator (built-in battery)      1 set x test leads      1 x USB cable            Only the above package content, other products are not included.
