What is ESR of capacitor? There is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C), the impedance become small, and we can then measure the true series resistor value. A bad E-capacitor will have larger ESR and create large ripple rather than filtering noise. Normally, a big capacitor is larger than 3 ohm. Using this theory, we can measure the capacitor is bad/ damaged or good in condition. Because our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test. Because this low testing voltage, it cannot turn on the semiconductor inside a circuit under testing. During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not. Note: - Accuracy maybe affected by the test lead’s length and contact point resistance.(Standard test leads is 15cm) - PLEASE DISCHARGE THE CAPACITOR BEFORE TESTING, you can use a screwdriver to short circuit, or series with a resistor around 10 ohm and short for 5 to 10s. There is 2 fast diode inside the meter to prevent high voltage, but it is important to discharge the capacitor firstly, as it is a large surge current and voltage and may damage the meter. Package Content 2 X ESR Capacitor 2 X Pair test clips Operating Introduction: POWER ON Press and hold the ON/ OFF circle orange button for 2 to 3 second to power on. Press and release the ON/ OFF button to shut down meter. AUTO/ MANUAL mode: Auto Range: Press and release the RANGE button and at the first line of LCD will show “AUTO:" At auto mode meter will automatically select the best range to detect. Manual Range: Scroll the manual range from 1R, 10R and 100R range by press and release the RANGE button In LCD will show MANUAL at first LCD line and show at second line: 0-1R, 1-10R and 10-100R. 1 Key Zero: Short circuit the test leads’ terminal, cancelling the wire resistance. Press and release the “ZERO" button, LCD shows “ZERO" and wait the zero disappear. If you are using the meter array socket, you need to use a short pin to short circuit to set zero. Backlight: LCD backlight will on during power on Auto Sleep: Around 10 hours for not testing, it will shut down automatically to save power. OVERFLOW or OL: Display overflow when the value is out of range, you can check that you are zero correctly. ESR TABLE: It is for reference only, different manufacturer of capacitor has different ESR, better to test a good cap ESR and compare with what you are testing, usually bad cap with higher ESR few times larger than good one. SOFTWARE ESR: Put the 25V Electrolytic capacitor value to LCD, and compare, GOOD if C < XXuF, means the capacitor maybe good condition if it is less than XXuF Specification: Range Accuracy (After Zero, tested with 1,10,100R resistor) Refresh Time (Manual Mode) *Auto mode take 0 to 2s more time depend on value 0.000 to 1.000R 1%+2Digit ~0.4s 1.000 to 10.00R 1%+1Digit ~0.4s 10.00 to 100.0R 2%+1Digit ~0.4s Accuracy Up to 1% (detail on above table) Wide Measurement Range: >1uF (for 0.1uF the error will be larger on equation 1/(2*pi*F*C) @ 100Khz ) High Resolution 4 digit, or 0.001Ohm @ 1 Ohm range Measuring voltage <~40mV RMS (TESTING VOLTAGE) Clamping voltage ~0.15V (open voltage) Battery 2X AA 1.5V battery Operating current 0.02A Welcome to our store!We supply many products including computers accessories, camera & camcorder accessories, phone accessories,car accessories & Consumer Electronics.High product quality, reasonable prices, excellent customer service and a reliable credit standing is our tenet.
