Follow along as Erik troubleshoots this Simpson 260 - Series 4 VOM with a problem on the DC volt ranges. A look at the schematic is also included. #testequipment #electronicsrepair #learnelectronics
Thanks for trying to get this meter working again. They are quality instruments and they still have applications today that cannot be handled with DMMs
@@RPike-bq3xm Yes, zero EMI emission environments. One in particular I know of was a physics lab conducting experiments to measure the EM emissions from various materials under various conditions. The detection system needed to be calibrated using equipment that had zero EMI emissions, for obvious reasons.
Excellent meter. Still made. I use one all the time. Makes you understand what you're attempting to measure. If you purchase new in 2024 between 550-750 dollars.
Wow, I didn't know that, I found a place where they sell it (ITM) probably made in China ? same quality ? is there a market for that ? I have an old Simpson 303-Xl, still working, I love it.
@@levent8208 They are Made in USA. Still a market for them. Several areas still use them. A couple are power monitoring and in EMI free testing environments.
I love these meters too. I was taught on the Simpson but in less than a years time Fluke came out with the 8060A(B) and the company went with that for any new purchases. Reading any common return AC on Airliners made them wig out. For some reason, I don't have that issue anymore.
330+470 also conveniently adds up to exactly 800. I'd guess most of the resistors have aged up slightly over time, I'd look at ordering new ones (R10, R12, R14, R15) for the next time you need to make a buy from a supplier.
This series 4 version and other earlier version models used a standard D cell and four AA's. Later models starting at series 6 and newer used a D cell and 9volt battery.
