1) On the range under 20nF, setting the zero adjust switch till the LCD displays “000” ( but it must insert the
test leads or SMD test clip);
2) Insert the capacitor under tested to the “COM” or clip by test leads, the value will displayed on LCD, which
will read as unit of the selected range directly. If it displays “1”, it means over range measure. If there
is “1” or “00” before the displayed select a lower range to increase the measurement resolution.
Note
1) If the capacitance under measured is unknown beforehand, should set the range knob from the lower to the highest
range,
2) If capacitance breakdown, it will display over range in all ranges; when there’s a lower leaky capacitance,
it will display over range or a big value which is much bigger than the normal value. If turn off capacitance,
the reading will display “0” at all ranges;
3) When test the small (pF) capacitance, the test leads more short more better, when measuring, test points of
test leads should be close to the pin of capacitance under measured to zero adjust, thus can get a higher accuracy.
4) When use any test leads, please remember the test leads perhaps lead to a bigger capacitance. Firstly, it should
measure the capacitance value in the condition of the test leads is out of measurement, write down the
open-circuited value and deduct it from the test value, it will get a correct test result, this result is the
same under the other test condition;
5) Many capacitors (especially the electrolytic capacitor) have wide capacitance of condenser. If the test result
is bigger than the nominal value, there is no necessary to be surprised at it, except the blocking capacitor.
Usually the test result is seldom smaller than the rated value.
6) When range changes, and the test value have significant changes, it usually can examine the resist of leaky
capacitor. At the low range, the existent effect of leaky capacitance can reduce.
3-4 Inductance measure way
1) Set the function knob to a proper inductance range;
2) Insert the inductor under tested to the “COM” or clip by test leads, the value will displayed on LCD, which
will read as unit of the selected range directly. If it displays “1”, it means over range measure. If there
is “1” or “00” before the displayed select a lower range to increase the measurement resolution.
Note
1) If the range under measured is unknown beforehand, should set the range knob from the lower to the highest range,
2) In order to avoid leading into the stray induction, should use the short wire when the tiny inductance;
3) This meter can’t be used to test inductance’s figure of merit. e.g.: it perhaps gets a wrong reading when
test the inductance of resistance.
4、Auto power off
The meter will be into sleeping mode when stopping working for 20 minutes; if you want to measure you should restart
the power. It won’t be power off when it LCD display full range 20%.
5、Maintenance
Do not try to modify the electric circuit.
Note:
1) Keep the meter away from water, dust and shock;
2) Do not store and operate the meter under the condition of high temperature, high humidity, combustible, explosive
and strong magnetic place;
3) Wipe the case with a damp cloth and detergent; do not use abrasives and alcohol;
4) If do not operate for a long time, should take out the battery to avoid leakage;
5) When signal displays, should replace the battery following the
steps:
1) Take off the holster. (see the fig.)；
2) Unlock the screw and remove the battery case.
3) Take out the old battery and replace the new one. It's better to use
alkaline battery for longer life
4) Fit on the battery case and lock the screw;
5) Fit on the holster as the opposite way.
