Voltage output :5-AVO 6-GND

Current is commonly used in active mode: our output (4-AIO 6-GND) corresponds to the PLC's I+1-!

3

Current passive mode: our table 3-AI+ external access 24V+, and then output from 4-AI0, control the external 24V current; Our meter is equivalent to an adjustable resistor; Therefore, it is called passive mode, direct measurement can not detect the current, and can directly replace the passive two-wire pressure sensor wiring

Great product. Work as advertised

Works reasonably well. Bought 8 of these for testing analog inputs on panels. Like the ability to simulate both passive and active 4-20 ma circuits and the adjustable knob rate. Battery lasts 30 - 60 minutes in the modes we use them in. We use these with a USB power strip and just plug them all in. USB cords that ship with the units are short, ordered longer ones. Devices tend to lock up every couple of days, just power cycle them to clear. Instructions aren't clear but what else is new. Not too hard to figure out.

I'm designing a system that uses both 4-20mA and 0-10V sensors, and this thing was so handy during our hardware validation. Recommended!

This works just like it is supposed to. A bonus is that it feels substantil. The knobs, switches, and other hardware don't feel cheap like a lot of these types of devices. I am pleasantly surprised at the bonus level of quality.

Worked great. Used it to Troubleshoot a frequency drive. Was able to determine the analog input on the drive had failed. Was able to use the other input on the drive when replacing the board that sent the 4-20 mA signal. Saved me from possibly damaging the $1600 new board. Paid for itself on the first use. Great tool to have in your arsenal for troubleshooting. Would definitely recommend it to anyone.

This works exactly as advertised. Using the knob to adjust settings is tricky, but once you figure it out, it works great. Very handy for use as an analog signal generator.

Very good product with built in battery which makes it very portable. I can move it to where I need to generate a 4-20mA signal easily.And also used for give the 0-10 V

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.

If you do any service on control systems you need this ! It will help you setup and troubleshoot 4-20 controls quick as a jif. It's accurate and fairly durable - I've already dropped mine a couple of times and still works and is accurate.Best of all is it's low price.You can quickly determine if the sensors , wiring or programming is giving you the wrong information and wrong readings. A couple of quick connections and bam - problem identified ! This will pay for itself probably the first time you use it, defiantly when you can 100% show some one they have a bad sensor.I don't write many reviews and usually as a warning to others about bad products this is the exception. IT IS GREAT !The only negative thing I have to say about it is I wish it had a little case to protect it somewhat in my tool bag.I'm buying another so I can check to sensor circuits at the same time, these are so reasonable you can.
