Chroma 11025

The 11025 LCR Meter provides a powerful combination of features designed to maximize productivity in all testing environments. The 11025 LCR Meter can also measure DC resistance, turn ratio, and mutual inductance of transformers. It is suitable for pulse transformers or LF coil evaluation. The optional Chroma A110207 Transformer Test Fixture when used with the 11025 can measure both the primary and the secondary parameters automatically by changing the internal relays on the 11025. There is no need to change the connections required for measuring transformer parameters. Adjustable internal DC bias current source can be up to 200mA (constant 25Ω) which is a standard function, as the right tool for inductance inspection of telecom transformers and small power chokes under DC bias current.
