Can be used home, garden, caravan, camper, marine. Low power consumption, super hydrostatic bring extreme atomization enjoyment. Excellent quality, strong stability,but low noise.Hot 4-20MA 0-10V Adjustable Signal Generator Process Controlling Signal Calibrator Signal Generator Sources 0-20MA Simulator1. Internal reverse and overcurrent protection, 30V protection voltage.2. Built-in one single 3.7V lithium battery power supply; the using time varies, based on the usage (It can be more than 6 hours with 20mA continuous output).3. With internal battery voltage hint, (UV light)when the undervoltage light is on, please turn off the charging.4. Do not use for a long time, please charge once every two months. Charge with micro-USB (Not Included). Operating temperature range 0-50 degrees Celsius.5. The signal generator is mainly used for debugging of industrial field PLC, process instrumentation, electric valve and so forth. The signal generator is small and light but has a long standby time and high precision.VC Conversion Function:This function is mainly used for some temporary voltage and current conversion, such as converting 0-10V input to 4-20mA output.VC active conversion: converts the voltage signal input into an active current signal output VC passive conversion: converts the voltage signal input into a passive current signal outputC-V conversion: converts the current input signal into a voltage signal outputThe function rules consist of several parts: VC conversion switch, conversion mode, voltage upper limit, voltage lower limit, current upper limit, current lower limit, and overrange.Specifications:Name: Signal GeneratorActive current output: range: 0-24mA; resolution: 0.01mA; maximum load: 750Passive current output: range: 0-24mA; resolution: 0.01mA; external power supply up to 30V.Voltage output: range: 0-12V; resolution: 0.01V; maximum current 30mA24V voltage outpu
