FreeShping Upgrade MESR-100 AutoRanging In Circuit ESR /Low Ohm Meter Up to 0.01 to 100R
Features:/p>
JINGYAN MESR-100 V2 Auto-ranging ESR and Low Ohm Meter
Measuring range from 0.001 to 100.0R, support IN CIRCUIT Testing.
Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of manufacturer.
In the market, there is some technique using short pulse method to testing, but the value will be varying vs the capacitance and sometimes reading is different from the manufacturer's value.
What is ESR of ?
There is a series inside , using 100kHz to remove the impedance 1/(2*pi*F*C), the impedance become small, and we can then measure the true series value.
A bad E- will have larger ESR and create large rple rather than filtering noise. Normally, a big is larger than 3 ohm.
Using this theory, we can measure the is bad/ damaged or good in condition.
Because our ESR meter only applies le than 15mV DC or peak to peak on a good , 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 is good or not.*Dual terminal, for fast and easy inspect general or , a printed ESR table for fast che
Compare MESR100 old V1 and new V2 Improvement:/p>
1) Change square wave to sine wave 100 KHz, reduce square wave’s high frequency component, and affect the reading paing the test leads and .
2) Higher Resolution up to 0.001 ohm.
3) 128X64 dot matrix LCD, with more larger value display and information
4) Embedded 25V table at LCD, auto display the is good or bad reference to common 25V electrolytic .
5) New plastic case, curve design for hand carrying. New stand for 60 degree stand on desk.
6) Use 2X AA battery, more convenience and longer battery life than 9V battery.
7) Support external USB power, using standard micro-USB port.

*Accuracy maybe affected by the test lead’s length and contact point resistance.
Standard test leads is 15cm, for longer test leads need special shielding to affect the EMI inference (Can contact s’ person for more detail)
1) 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 )
2) High Resolution: 4 digit, or 0.001Ohm @ 1 Ohm range
3) Measuring voltage: 80 Hours
Operating Introduction:/p>
1) POWER ON
Pre and hold the ON/ OFF circle orange on for 2 to 3 second to power on.
Pre and release the ON/ OFF on to shut down meter.
2) AUTO/ MANUAL mode:/p>
i) Auto Range:/p>
Pre and release the RANGE on and at the first line of LCD will show “AUTO:"
At auto mode meter will automatically select the best range to detect.
ii) Manual Range:/p>
Scroll the manual range from 1R, 10R and 100R range by pre and release the RANGE on
In LCD will show MANUAL at first LCD line and show at second line: 0-1R, 1-10R and 10-100R.
3) 1 Key Zero:/p>
Short circuit the test leads’ terminal, cancelling the wire resistance.
Pre and release the “ZERO" on, LCD shows “ZERO" and wait the zero disappear.
If you are using the meter array soet, you need to use a short pin to short circuit to set zero.
4) Balight:/p>
LCD balight will on during power on
5) Auto Sleep:/p>
Around 10 hours for not testing, it will shut down automatically to save power.
6) OVERFLOW or OL:/p>
Display overflow when the value is out of range, you can che that you are zero correctly.
7) ESR TABLE:/p>
It is for reference only, different manufacturer of 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.
8) ESR:/p>
Put the 25V Electrolytic value to LCD, and compare,
GOOD if C
If you don’t use the stand, pre and push the lo position:/p>
