Upgraded 4-20ma Signal Generator, for Plc Debugging, Servo Motors

Upgraded Function: 1. The range of output voltage is expanded to -10V to 10V, high recommended for the servo motors which needs positive inversion and consecutive speed regulation; 2. It can output real 0V, help the light dimmer control the lights to go out completely, and eliminate flutter when control the servo motor; 3. It adds functionality of call output values quickly, more convenient for rapid debugging and production.Power Supply: built-in rechargeable battery (charged via micro-USB port), external micro-USB-5V, external power DC 15-30V, each way makes the generator workVoltage Output: -10V-10V, precision is 0.01V; Current Output: 0-22mA, precision is 0.01mA; Rotate the encoder knob to adjust output voltage/current; The range of output voltage/current can be setc; Both of them can be calibrated; Adjust and set value types (voltage/current) depends on the displayed mode.Multiple Display: just push the small button to switch the display mode between voltage and current, you can also follow the instructions to switch 0-100 percent or 0-50HZ display.Product Dimension: 3.94inch x 2.36inch x 0.78inch (100mm x 60mm x 20mm), thiner than the old version, more portable and convenient.Colour:BlackMaterial:plasticPackage Contents:1 * new version signal generator1 * Micro-USB power cable4 * alligator clips6 * cold pressed insulated terminas1 * flat head screw driver(Random colors,specified colors are not accepted)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
