The ESR capacitor tester is used to measure the ESR value of capacitance so that users can know the capacitor(mainly electrolytic capacitor) is normal or not. It's practical for use and it can measure the range between 0.1uF to 10uF of capacitor.
Features:
Adopts microcontroller port for direct synchronous detection, the microcontroller generates square wave measurement signal and precise synchronization signal.
The measurement method is similar with LCR digital electric bridge.
The RC series expand to other wave response, calculating Rs and Cs through previous and present series so as to improve the measuring accuracy of CBB capacitance of high-Q(under 2uF).
Uses over sampling technology, the AD converter is increased from 10bit 12bit, needing only one range for measuring 0.01~20 ohms and the lower limit with margin.
With auto-zero function, zero drift is reduced several times and long time stability. Usually use, generally without zeroing.
Adding drift compensation circuit, making the detection circuit structure close to the bridge circuit, drift small.
With small inductance measurement function, simultaneously measure the DC resistance.
Only one button for operation, easy and convenient to use.
Can precisely measure the capacitor ESR(>0.1uF) and can also measure the ESR of CBB capacitor. The resolution is 0.01 ohm.
Measures the capacitor's capacity between 0.1uF~10uF. The resolution is 1uF.
Precisely measures non-inductive resistance less than 20 ohms. The resolution is 0.01 ohm.
Notice:
1. Before the test, please remember to discharge the capacitor.
2. Press the button, turn on and test.
3. Press 3s for clear operation.
4. Long press 5s to turn on the backlight.
