User Manual

The SIM-ALP2 can simulate a 2 wire 4-20 mA loop powered device, a 4 wire 4-20mA current source without an external power supply, or a 0-10VDC signal without an external power supply.

Simulating is easy in 1 mA/V or 0.1 mA/V increments by simply clicking the up and down buttons.  Each point can be individually calibrated to suit your needs.

With a range of 0-22mA and -10VDC to +10VDC, it can also simulate over and under range conditions.

Comes with carrying case and alligator leads.

Great value when you don't need an expensive calibrator such as a Fluke 707.

    Analog Simulator and Generator

    Posted by Michael G on Jun 23rd 2020

    This is one of the best tools out there. I had got one a few years back and lost it. I had to have another one. Small enough to fit in your palm. I work in the industrial HVAC industry and this is one of the most helpful troubleshooting tools I have ever had the pleasure of owning. Accurate enough for calibrating controls to get you by in a pinch until you can get a higher end tool. Affordable enough to buy out of your own pocket if your work won't approve an expensive unit. 5 starts I'm my book!

    Compact analog simulator that works great to source and simulate 4-20mA signals. This is a must have for troubleshooting analog inputs and cable runs! It also comes with a nice storage case. Highly recommended!!!
