I can move it to where I need to generate a 4-20mA signal easily.And also used for give the 0-10 V ### ⭐⭐⭐⭐⭐ Nice Little "Test" instrument *by on Reviewed in the United States 12 January 2023* I haven't spent time to look at its stability or noise, but this little gadget does a lot for the price.I am primarily using it as a DC voltage source over a +/-10V range for testing/debugging electronics. I'm not using the 4-20mA function (presently). It has 10mV of resolution as a voltage source.But it comes with an internal rechargeable battery....Lithium ion battery ( I think) a USB port , plus USB cable, to charge the device.The knob will twiddle a "selectable" 100mV digit or 10mV digit.... fairly easy to configure, but not intuitive. You need to reference instructions.You can also configure more behind the scene settings with the knob (voltage range for example). Even less intuitive....it requires a password. Don't toss the instructions.I think it would have been more slick to have two push buttons left/right direction ... left/ right to select a digit...which gets "highlighted"...either by flashing the digit or extra brightness on the selected digit when in edit mode. Then the knob could twiddle the selected digit up and down. What is the price of two extra left right push buttons. :-)I measured its out-of-the-box accuracy and it was pretty close.....off by ~200uV of "offset" in the negative direction...its linearity was pretty good....+/-1V was off by less than 1mV, +/-10V was off by less than 10mV....so mine had sub +/-0.1% kind of accuracy with a 200uV floor.If I see any quirks, I'll update my review, but don't think I would expect more for the price. It delivers.I have promptly put in an order for a second device, just to have one around while the other may be charging. ### ⭐⭐⭐⭐⭐ Good Value and Simple to Use *by on Reviewed in the United States 9 October 2025* SImple to use. Battery was charged when I received so I was able to play with it right away. Also has capability to run off 24VDC power or USB adapter (comes w/cord but you'll need the USB power supply/phone charger)Good value; I'm not looking for a calibration quality device so it fit my needs.I will be using it as a 4-20mA source. It outputs at 24VDC in the mA generator mode. It was accurate enough for what I will be using it, mainly troubleshooting or modeling. I don't need to be highly precise. I noticed the signal bounced somewhat, but it was in the magnitude of .01's. This difference just as well could be from the precision of the controller/PLC that I was connected to.Comes with a USB power cord and little tweaker screwdriver. Nice to have when you are working in the field. ## Frequently Bought Together - Adjustable 4-20mA Signal Generator Current Voltage Analog Simulator 0-10V/0-22mA Signal Sources for Value Adjusting PLC Controller Panel LED Testing Calibration - DROK 4-20mA Generator, Adjustable Signal Generator, DC 0-10V 0 4-20mA Current Voltage Analog Simulator for Value Adjusting PLC Panel LED Testing - Riiai Upgraded 4-20mA 0-24V Current Signal Generator, Current Voltage Adjustable Analog Simulator, Real-time Curve, Multiple Signal Types, 3000mAh USB Rechargeable, Preset Value, for PLC Testing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/453199310-adjustable-4-20ma-signal-generator-current-voltage-analog-simulator](https://www.desertcart.ec/products/453199310-adjustable-4-20ma-signal-generator-current-voltage-analog-simulator) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-01*
