Digital Voltage Signal Generator 4-20mA 0-10V 0-20mA Current Transducer Professional Electronic Measuring Instruments Ear: 12x8 cm/4.7x3 inches This small portable voltage and current generator can be used for scientific research, laboratories, corporate factories, electrical maintenance, etc. Output power: < 20 mW This single voltage and current generator is the most commonly used instrument for electrical testing by electrical engineers and technical personnel during the installation, debugging, checking and maintenance of electrical equipment on site. Plug-in terminal blocks, safe and convenient wiring. 4-digit high-resolution digital tube, screen brightness is uniform and adjustable (brightness 1-8). Aluminum knob cover, galvanized buttons, high quality film, charge indicator, battery switch. Three ways of power supply, external power supply, DC5V micro USB, built-in lithium battery. As long as it works, it can be connected at the same time. External DC 15-30V power supply, which can share 24V PLC power supply and other equipment. Universal MicroUSB interface, can be connected to power bank, charger, computer USB port, etc. On the normal operation screen, save the voltage and current value, set the encoder to write, after releasing the OK button, ... will appear on the screen, which means that the save succeeded. Reset directly shows the saved value, there is no need to adjust the parameters za every time you turn on the machine, which is very convenient. Easy to carry and small, best choice for on-site debugging.
