FNIRSI 0-12V/0-4-24mA Handheld Positive Negative Voltage Current Signal Generator(Without Battery)

1. The 0-10V/0-22mA voltage and current source signal generator is the most commonly used electrical test instrument by electrical engineering technicians during the installation, debugging, overhaul and maintenance of on-site electrical equipment. It is also used in scientific research, teaching experiments and other applications. It is also widely used in the field of2. In smart mode, the voltmeter automatically measures voltage, resistance and continuity. It can identify the measurement content and select the resolution range, making the measurement more convenient and faster.3. Easy to use, USB direct plug-in power supply, no need to manually replace the battery, more convenient4. Micro USB universal interface, can be connected to power bank/charger/computer USB port, etc.Plug-in terminals for safe and convenient wiring5. 4-digit high-definition digital tube, uniform and adjustable display brightness (1-8 levels of brightness)6. Set a voltage and current value, click the encoder to save, and restart to directly display the saved value. There is no need to adjust parameters every time you turn on the machine. It is highly practical.7. The small handheld signal source is easy to carry and a powerful tool for on-site debugging.8. Size: 89 x 69 x 28mm9. Weight: 95 grams
