Features:
JINGYAN MESR-100 V2 Auto-ranging capacitor 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 capacitor 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 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.
*Dual terminal, for fast and easy inspect general capacitor or resistor, a
printed ESR table for fast check
Compare MESR100 old V1 and new V2 Improvement:
1)
Change
square wave to sine wave 100 KHz, reduce square wave’s high frequency component,
and affect the reading passing the test leads and capacitor.
2)
Higher
Resolution up to 0.001 ohm.
3)
128X64
dot matrix LCD, with more larger value display and information
4)
Embedded
25V capacitor table at LCD, auto display the capacitor is good or bad reference
to common 25V electrolytic capacitor.
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.

Standard test leads is 15cm, for longer test leads need special shielding to
affect the EMI inference (Can contact sales’ person for more detail)

Operating Introduction:
1)
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.
2) AUTO/ MANUAL mode:
i) 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.
ii) 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.
3) 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.
4) Backlight:
LCD backlight will on during power on
5) Auto Sleep:
Around 10 hours for not testing, it will shut down automatically to save power.
6) OVERFLOW or OL:
Display overflow when the value is out of range, you can check that you are zero
correctly.
7) 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.
8) 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
9) PLASTIC STAND:
If you don’t use the stand, press and push the lock position
