Review: Great sensor simulator - I needed a way to simulate a 4-20mA signal, as from a piece of industial equipment. I needed it fast and my multimeter did not have this function (I know of others that do). I did have a little trouble figuring out where to connect the wires for simulating 4-20mA and then where to connect my wires to simulate 0-5vdc. But even with my very limited electronics experience and my (very) cheap (free) multimeter (from Harbor Freight), I was able to figure out the polarity and connections for 4-20mA and 0-5vdc. The manual was not real helpful to me, so I've included pictures labeling where I connected my wires. But I believe the Fluke multimeter that would simulate these test signals is several hundred dollars. In the meantime, this device works great. -T
Review: Great value - I use this for PLCs and testing. It works great and it's fairly accurate. I haven't seen it off by more than .1% which is fine for most uses.

## Features

- Power Supply: external connection micro USB-5V or external power DC 15-30V, each way makes the generator work, both ways also can be connected at the same time. Battery is not included.
- Voltage Output: DC ±10V, precision is 0.01V, rotate the encoder knob to adjust output voltage, can be calibrated.
- Current Output: 0-22mA, precision is 0.01mA, rotate the encoder knob to adjust output current, can be calibrated.
- Multiple display: just push the small botton 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: 3.94” x 2.36” x 0.79” (100mm x 60mm x 20mm), portable and convenient.
- Battery model: DC 3.7V 1000mAh 803040

## Questions & Answers

**Q: Can i use this as a one pulse per second generator?  I don't see a way to adjust frequency**
A: Hi, this device is designed to simulate voltage and current signal, can't be used as a one pulse per second generator.

**Q: how do you install a battery?**
A: It does not come with a battery but you can buy a Lipo Rechargeable Lithium Polymer ion battery pack. The battery pack comes per-wired with the proper connector. Verify the connector pin polarity is correct before connecting. I just installed the YDL 3.7V 2800mAh 623360 (https://www.amazon.com/gp/product/B07BTRLKPT/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) and it works fine. To disassemble

     1.  Ensure battery switch is in the OFF position.
     2.  Remove knob from dial encoder.
     3.  Remove nut from dial encoder.
     4.  Use small screwdriver to separate top from case (slots on one end to make this easy to do).
     5.  Remove 4 screws holding pcb in case
     6.  Remove pcb and flip over. Two pin JST connector on bottom for battery pack connection (polarity is marked)
     7.  Assuming polarity of battery pack connector matches pcb connector just plug the battery pack in.
     8.  Mound battery pack in case with double back tape or velcro pieces.
     9.  Reassemble in reverse order.
The unit should power up when battery switch is placed in ON position.

**Q: Can this output a current duty cycle?**
A: Not that I’ve found. Instructions a little sparse, Nicky made unit though, and reasonably accruate, certainly for the cost.

**Q: To the manufacturer...would you consider upgraded terminal block to the quality cam lever action terminal block instead of the screw block.**
A: If one is considering a high-current application, a Cam-Lever type terminal will not provide the compression needed over a wide area for a proper connection.

### ⭐⭐⭐⭐ Great value

I use this for PLCs and testing. It works great and it's fairly accurate. I haven't seen it off by more than .1% which is fine for most uses.

### ⭐⭐⭐⭐⭐ This device is excellent for the money.
*by O***F on February 21, 2019*

This simulator will do 0-10, 2-10 2-5, 0-3.3 Volts and 0-20, 4-20, 0-22 ma. It will display output value, percent of range or 0 to 50 HZ (not so useful in the US). It can be calibrated and the encoder steps can be adjusted. It is not likely to hold up to daily use in an industrial environment but for someone like myself that on occasion needs to simulate a transducer, it is perfect. I also purchased a micro usb to micro usb charging cable. I can use my phone to power the unit on the rare occasions that I need it without worrying about batteries or separate power supply.
