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:
