Div_by_zero Posted February 13, 2015 Report Posted February 13, 2015 Looking for a cheap, simple loop calibrator. I intend to it as a simulator to check analog code...for example when temperature climbs above a trip point, do I get an alarm or not, things like that. For this reason, extreme accuracy is not needed, and I would hate to drop $900+ on something like a Fluke 707. Also, due to the fact that I often have multiple analog inputs on a panel and they often work together with each other in the code, low cost is even more important as I would like to get a few of them, as many as 4. Any suggestions? Thanks. Quote
Mendon Systems Posted February 13, 2015 Report Posted February 13, 2015 These do work and they're not expensive but not the quality of a Fluke either. They have a couple of different models. http://www.ebay.com/itm/H706-Process-Loop-Calibrator-DC-Current-Source-Meter-/130600016484?pt=LH_DefaultDomain_0&hash=item1e685e1a64 Quote

It even looks the same. I bought one of these after I lost my Fluke 789. These days I find myself spending most of my time sitting at a computer, often doing remote access work, so I couldn't justify spending $1100-$1200 on a 789 again. So far the knock-off has served me well, and has been accurate to at least 1%, if not better. It even has the "Loop Power" feature of the Fluke 789, where you can power up and test a transmitter with your meter. Edited February 13, 2015 by MrAutomation Quote

Div_by_zero Posted February 15, 2015 Author Report Posted February 15, 2015 Mickey, Absolutely perfect, exactly what I was looking for, thanks! MrAutomation, I've been interested in that "other yellow brand" for a while now. How close to the real deal (Fluke) do you feel those are? What, if anything, makes them weaker than a Fluke? NOT to knock Fluke in any way/shape/form, but certainly a finite percentage of what we pay for Fluke equipment is for the name itself. Thanks. Quote
