MCH-108 Digital Multimeter: What is the accuracy of the device?

Tue, 29 Aug 2023 14:51:36 -0700

Hey all!
I've been eyeing the market for a digital multimeter and I'm definitely interested in this model, but unfortunately there aren't any technical specifications listed on the store page for the product. I just wanted to know if anyone knew what the accuracy of this model is? (i.e. To how many decimal places can this model measure confidently)

Thank you for your help!

MCH-108 Digital Multimeter: Am I testing continuity correctly?

Mon, 09 Dec 2024 03:18:18 -0700

I recently bought a ifixit multimeter and I tested it out to see if it was working properly. I tried out the different modes and they worked until i tried out continuity. I took a battery that i knew was charged and tried to test it out my multimeter. I turned continuity testing mode on and touched both probes together to see if it would beep and it did. I then took the red probe and held it on positive terminal and put the black probe on negative but the multimeter didnt beep. I was very confused. I then got the idea to put the red probe on the negative terminal and the black probe on the positive terminal and guess what, it beeped.

My question is when testing continuity in a battery am i supposed to put red probe to positive and black probe to negative or am i supposed to do red probe to negative and black probe to positive.

MCH-108 Digital Multimeter: Is the continuity test suitable for sweeping IC pins?

Looking to buy my first multimeter. I have access to an old RadioShack multimeter that struggles with continuity, often taking a full second or more before beeping when the probes are shorted. I am looking for a multimeter for home projects and small repairs/tinkering so accuracy isn't necessarily my top concern, but responsiveness is as it will help reduce uncertainty and be more enjoyable to use.

If I quickly drag the probe across IC pins, will it:
A. Beep if a single pin is shorted to the other probe (not likely to miss a short)
B. Be reasonably noticeable to the average person. (loud beep on quick short)

I don't need it to be latching, just reasonably usable for this use case. I have used multimeters very briefly and am basically completely new to the hobby.
