Dec 17, 2017 - Modifying your Cen-Tech 92020 digital multimeter's backlight to operate constantly. This meter differs from the #98025 and #69096 by way of an orange. And if you're new to your electronics hobby, the manual range.

This meter differs from the #98025 and #69096 by way of an orange backlight for the display. In addition to my being a sucker for almost anything that lights up, the backlight does lend considerable utility to these inexpensive meters. There's a dollar worth of difference between the two, and I'm certainly willing to spend the dollar. ( Update as of July 2018: HFT placed these on in December of 2017, with a price of less than $4!

It is highly likely that they have since sold out of all Harbor Freight stores. They are definitely no longer on the HFT web site and I have not seen them in any HFT store as of a few months later.) You'll find these meters sold under many different names, colors and model numbers, but they're all the same thing: variants of the Chinese DT-830 manual ranging multimeter. I'd never recommend them for use on the AC powerline (mainly because so many of them really aren't very safe) but for low voltage DC and many resistance measurements they're as good as you'll ever need. And if you're new to your electronics hobby, the manual range selection forces you to think about what you're measuring and why. That might slow you down enough to avoid making a mistake, or it might not. Even if it doesn't, or if you decide that working with electronics isn't your hobby, you aren't out much. Or if you do get into electronics repair, you can easily move up to a better meter in time.

I like the backlit variant (and wish Harbor Freight would, if just the one time, offer them for free with a coupon) because almost any higher quality multimeter has one and you'll be surprised how often you find yourself working with a multimeter where there isn't sufficient light. The problem is that the backlight only stays on for about five seconds. Here again, you'll be surprised where you find your hands busy enough, or that you need to concentrate without the hassle of having to turn the backlight on.

Wouldn't it be nice if the backlight on the #92020 meter could just stay on? Why, yes it would! I'd been thinking for a long time that this couldn't be that hard to do, but I never sat down and tried to figure it out. Ecowater systems water softener manual. Here's what you do. Let's talk about SAFETY. You're more likely to hurt the multimeter than you are anything else here, and it's not like replacing it is expensive. However, the number of stupid people in the world is absolutely mind boggling. Risunki protiv kureniya grip.

Oh sure, we've all had our moments where we did dumb things. Yet we can all think of people who seem to exist only as a warning to others, or those that make you honestly wonder how they're even still alive. Make sure you aren't measuring anything with the multimeter when you go to modify it. Remove the battery before you work on the circuit board. Be extremely careful with a soldering iron and only work with solder in a well ventilated area. If you've never soldered anything before, don't make this your first project. Practice on some scrap circuit boards or components, build an or two and then come back here if you're still interested in doing this modification.
