Multimeter Not Reading Voltage
This circuit was only pulling 1.8mA at the time of measurement, not a lot of current. I understand it's due to some effect of the high impedance input and I think I could live with a little bit of that, even though my two older cheap DMMs Nayliner 12.106 visualizaciones 1:16 Multimeter Repair Part 1 - Duración: 10:31.

The multimeter should emit a tone (Note: Not all multimeters have a continuity setting, but most should). The reading on the multimeter is simply negative. Answer Questions Pin modem E173u-1? Multimeters are generally not autoranging.
Multimeter Not Reading Voltage
Warning! A soft knob is usually indicative of a shoddy meter. This is a feature that can benefit beginners and advanced users alike, as it’s easy to forget to turn the meter off at 2AM. the same #3 Like Reply Jul 17, 2009 #4 KL7AJ AAC Fanatic!
Most of my systems use more than 10mA so the 10A setting and port works well enough. If you try to measure the current with a blown fuse, you’ll probably notice that the meter reads ‘0.00’ and that the system doesn’t turn on like it should when you Purchasing a Multimeter Resources and Going Further Comments 2 View Paginated Print Tags Electrical Engineering Skill Start a Project Tools License Creative Commons tutorials are CC BY-SA 4.0 SharingIngenuity GitHub YouTube How Do I Know If My Multimeter Is Broken Switch to another language: Catalan | Basque | Galician | View all Cerrar Sí, quiero conservarla.
On our favorite multimeter, the 200mA hole is the same port/hole as voltage and resistance reading (the port is labeled mAVΩ). Multimeter Not Working Properly Here's my opinion: a well-designed multimeter should work fine after turn-on hooked to a 220 V supply. You will probably need to take it to a place that does repair and calibration on digital multimeters to have it repaired and tested. http://electronics.stackexchange.com/questions/52472/how-to-check-if-my-multimeters-fuse-is-damaged Everyone has his or her preference, but in general multimeters that have continuity are preferred.
We can test different parts of the circuit as well. How To Repair Digital Multimeter You should get a reading of 0 ohms (or infinity ohms if working with an analog multimeter). Not the answer you're looking for? Nothing bad happens!

Make sure the red probe is plugged into the 200mA fused port. find this The fuse blows to protect the meter. Multimeter Not Reading Voltage show more Hi! Analog Multimeter Not Working It should emit a tone indicating that power is free to flow from the VCC pin to the micro.
But don’t be surprised if you hear a short ‘beep!’ when probing. http://noipc.org/not-working/laptop-dvd-player-not-reading-disc.html If there is continuity (if you hear a beep), then you’ve got a short somewhere. Inicia sesión para que tengamos en cuenta tu opinión. As mentioned, we’ll need to physically interrupt the circuit to measure the current. Digital Multimeter Repair Manual
