signal generator  
Portable Multi Function Signal Generator SG-01                
This signal generator can measure or output multiple signals including voltage, current, TC, with LCD screen, silicone keyboard, simple operation, longer standby time, higher accuracy and programmable output. Its widely used in lab, industry local, PLC, process instrument, electric valve and many other area's debugging.
1. Voltage signal: 0-30V; 0-25mV; 0-100mV
2. Output and measurement.
3. Current signal: Active current 0-25mA, 4-20mA, output and measurement.
4. TC (thermal couple): K, E, J, T, R, B, S output and measurement.
