商品説明
to join the temperature drift compensation circuit, which makes the detection circuit structure is close
to the bridge circuit, temperature drift is very small.
Measurement conversion of 7, only one button for ESR and the inductance and power switch.
2、Specifications

特記事項
- using SCM port directly synchronous detection, single chip to generate square wave signal measurement and precision of the synchronization signal
- using a method similar to LCR digital bridge detection.After the 90 phase synchronous detection, obtain the capacitance. Electrolytic capacitor used frequency method to measure the capacity, extends the measurement range.
- to solve nonlinear problems of constant resistance of encouragement, the square wave response of RC series expansion, and series prior two calculation of Rs and Cs,greatly improving the measurement accuracy of 2uF following high Q CBB capacitors
- the application of over sampling technique, use the12 bit AD converter , so just one range can achieve 0.01 to 20 ohm measurement.
- with automatic constant zero function, zero driftreduction decimal zero, ensure the long time stable.
