Title: 2D72 DMM spoiled [Print this page] Author: FatBoy Time: 2021-5-12 21:48 Title: 2D72 DMM spoiled Edited by FatBoy at 2021-5-12 21:49
Hello, my 2D72 cannot measure high voltage. Is there a fuse I need to replace? It can only measure low battery voltages like 9V or 3V. If I use it to measure 60V, it says 0.000mV. Same for AC measurement, I plug into the mains and it shows -0L.
Any help greatly appreciated. Thank you.

Please refer to this post.
From the photo, do you think R12 is also burnt? Author: FatBoy Time: 2021-5-14 15:24 Edited by FatBoy at 2021-5-14 15:26
Hello Amy, I have a problem. The shops in my country don't sell SMD resistors & definitely don't have resistors with tolerance of 0.1%.
Where can I buy those? Do you sell these parts?
Thank you for your help.

We can send them to you, but the freight is expensive.
Maybe you can purchase them on aliexpress. https://www.aliexpress.com/whole ... t=0603+SMD+Resistor Author: FatBoy Time: 2021-5-18 12:13
Hello Amy, what is the shipping charges like? I'm in Singapore, usually when I buy things from aliexpress, light items the shipping is about SGD5.
I've checked aliexpress, min order quantity for the resistors is 100pcs per resistance value, so if I order R12, R13, R14 & R15 that would be 400pcs total. So I don't know what to do with the remaining 396pcs after I repaired the DMM.
Please let me know your shipping charges. Thank you. Author: FatBoy Time: 2021-6-8 11:49 Edited by FatBoy at 2021-6-8 11:52
Hello Amy, can you sell me the parts please? The parts with such tight tolerance are impossible to find. With 0.1% tolerance at 1/16W, and value of 101K ohm, I cannot find it in Aliexpress or ebay.
Thank you.
