Repairing an HP 3438A digital multimeter
Jeff (aka K6JCA) did a repair of an HP 3438A digital multimeter and documented the whole process on his blog: This blog post is a record of my notes made while repairing an HP 3438A Digital Multimeter I had picked up last year at a local electronics swap meet. The 3438A is a 3.5 digit […]
Amazon’s cheapest multimeter teardown: The DT-830B
A teardown of Amazon’s cheapest multimeter the DT-830B by Electronupdate: Purchased the cheapest multimeter I could find so I could extract the integrated circuit. A surprisingly simple IC! The actual meter design was much as expected. Poor attention to detail for higher voltages, concerning lack of fuses on current measurements… pretty thin feeling probe set. […]
Vintage multimeter – Weston 6000
Teardown and repair of a Vintage multimeter – Weston 6000 by KuzyaTech: Another addition to my growing collection of vintage multimeters is this Weston Schlumberger Model 6000 meter from the mid 1970s The meter was listed as in almost like new condition except for a spot on the front panel. It came with (very rubbery) test […]
Agilent 34461A miniseries part 1 Histogramm and Cdf
Michael Rubitschka writes: Today I received a Agiltent 34461A Truevolt multimeter from Xtest.at the Austrian Agilent distributor. I plan to write some articles about this multimeter and especially about features which imho separates it from it’s competition. I am a Hewlett Packard / Agilent fan but I will try hard to be as unbiased as […]
Open hardware multimeter concept
EEVblog has a video about DIY multimeters. A few months ago the EEVblog forum talked about designing their own multimeter, so Dave made a video about his ideas on the subject. We’ve also toyed with the idea of an open source digital multimeter, but ready-made devices are so cheap and ubiquitous it hasn’t become a […]
Add auto turn-off to a cheap multimeter
Florin was tired of wasting batteries every time he forgot to turn off his multimeter. He hacked together an auto-shutdown: I bought this multimeter(Minipa ET-870C) a while ago for $17, great value. I got it because its nice to have around multiple meters for when you wanna measure both input and output voltage/current. I believe […]
Micropower data collection
Here’s Big Mess o’ Wires on micropower data collection: Hallelujah! After substituting an external 32768 Hz crystal as the timer clock source for my hiking data logger, I’ve reduced the sleep mode (LCD off) supply current to less than 0.01 mA! It’s actually below the resolution of my multimeter– the meter just reads zero. Previously […]
Can you identify this button?
arhi writes: I have some old (very old) KONTRON DMM 3002 bench top digital multimeter… there is a button on the thing that I have no clue what it does… So if you look at the pic, the button in question is the pressed one, or if not clear which one is pressed, the one […]
Lego minifigure multimeter
David Cook documented his Lego Minifigure multimeter build. …I created a device built from Lego bricks and minifigs that measures the resistance, displays the standard value, and speaks the resistance using text-to-speech (TTS). Thanks Frank! Via the contact form.
Diy Superprobe
Ben Ryves built his own version of the superprobe. having no need for some of the standard features he has modified the source for additional functionality. there is an excellent video of Ben demonstrating his superprobe after the break.
Multimeter buying tips
Here’s a tip on buying a multimeter: I would do a quick function check. Make sure the volt readings go to zero when you short the leads. If there is an AC outlet handy check to see if that reading makes sense. If you have a small battery in your pocket check that too. Make […]
