I regularly restore cars and work on troubleshooting vehicle electrical issues. Often times I get the call after everybody else has given up and on several obscure cars I have worked on, there have been no schematics of the cars' wiring harnesses. Of the cars I have built or restored several have been sold at the Barrett-Jackson auctions.
I stumbled onto the RedFish Instruments IDVM multi-meter app and hardware unit while looking at remote display voltmeters. I downloaded the demo app and installed it on my iPad 2. It basically looked like the readout I had on my multi-meters in my toolbox but there was one big difference - If I bought the hardware piece it gave the promise of truly remote multi-meter use. No more 10-15 foot wires used to extend my multi-meter leads to the back of a car while I was working under the dash or under the car.
I normally pay about $30-$40 for a decent digital multi-meter so why would I pay over $200 for a digital multi-meter? After buying the unit I had a lot of buyer's remorse before the unit even arrived. It showed up in a couple of days and Wow - what a surprise. I hooked it up and followed a few network configuration settings on the iPad and suddenly I was reading voltage on a battery sitting 15-20 feet away. A strange grin came over my face as I realized just how cool and useful this device and software are.
There are several reasons why this unit is a bargain:
#1 on my iPad 2 the RedFish unit gives me a display digit size of almost ¾" tall -- it has good contrast and is very easy to read. If viewing is not possible I can switch on the voice option and hear the voltage number from my iPad.
#2 When you are constantly testing circuits you are often checking for voltages or continuity and electrical switch operation. The RedFish unit allows you to hook up the remote unit and see the voltage or continuity results from a source on the car that is many feet away from an iPad or iPhone. Normally I'm trying to read some very small digits on a multi-meter while it is dandling from its wires in a constricted space. I often have to enlist a another helper to activate switches while I watch the meter results. No more of that for me!
#3 Having the capability to log or create a graph of voltage readings is something that I have not had the need for since I got my unit but I can recall several times from the past working with charging systems where being able to view a log or graph of voltages could be very helpful.
I think that this unit will revolutionize my electrical troubleshooting work. I highly recommend it to any car restorer or auto mechanic. I can't overstate how enthusiastic I am about this extremely helpful device.
I share this info out of my own person enthusasm for the app and device which I purchased at retail price from RedFish. I have no financial interest in the company or this product.
Richard, I knew if I planted that bug of an idea, you'd be able to figure it out. And in what, three days! WOW. Great job. Now I just have to install my non-remote voltmeter. It will probably just take me a week or so...
