### [2-Wire vs. 4-Wire Terminal Connection for Resistance Testing](https://info.triadmagnetics.com/blog/2-wire-vs-4-wire-terminal-connection-for-resistance-testing)

 Posted by [Bill Dull](https://info.triadmagnetics.com/blog/author/bill-dull) | January 8, 2025 | [0 Comments](https://info.triadmagnetics.com/blog/2-wire-vs-4-wire-terminal-connection-for-resistance-testing#comments-listing)

Precision digital multimeters (DMMs) and source measurement units (SMUs) offer two methods of measuring resistance: 2-wire resistance measurement and 4-wire resistance measurement. However, these techniques are not interchangeable because their readings vary in accuracy. While a small margin of error is acceptable for certain applications, other applications require greater accuracy to prevent \[...\]

### [How Does Quality Assurance Impact the Cost of a Transformer?](https://info.triadmagnetics.com/blog/quality-assurance-impact-cost-transformer)

 Posted by [Bill Dull](https://info.triadmagnetics.com/blog/author/bill-dull) | November 18, 2024 | [0 Comments](https://info.triadmagnetics.com/blog/quality-assurance-impact-cost-transformer#comments-listing)

Many customers believe that the cost of a transformer is limited to the amount that they pay upfront. At a basic level, transformer costs are determined by the time and materials used during the manufacturing process. However, the truth is that transformer costs are impacted by numerous complex factors, particularly when considering the impact on the overall system in which they're installed.
