## Description

Light brightness cannot be adjusted to be totally extinguished? Motors cannot be controlled to be stationary? Or the adjustable voltage cannot output 0V? Now for helping you better cope with these situations, DFRobot brings you a high-precision handheld signal generator, it has 2 power supply methods (micro USB/external power supply), 3 adjustment modes (coarse adjustment/fine adjustment/custom quick adjustment), 4-digit highlight digital tube for displaying data. Besides, it also offers current output, positive and negative voltage output, 0.05V accuracy, and linear output(accuracy can be calibrated). The module supports both passive and active current outputs, fully compatible with 2, 3, and 4-wire systems. The device comes with output short-circuit protection and power reverse connection protection mechanisms.It can be used to debug motor forward and reverse rotation, control light brightness, test external modulation signal source hardware or factory product voltage and current, etc.SpecificationPower Supply: Micro USB-5V, external DC15-30VOutput Voltage: -10~+10VOutput Current: 0~22mAVoltage Accuracy: 0.05VCurrent Accuracy: 0.05mAProtection Mechanism: output short circuit protection, power supply reverse connection protectionSize: 100*60*20mm / 3.94*2.36*0.79inchesDocumentsManualShipping ListHigh Precision Handheld Signal Generator x1Micro USB Cable x1Screwdriver x1User Manual x1Accessories Pack (Alligator clip, connector, etc) x1
