otherwise it will lead to the loss of extra heavy current, and it will have
over range display in all ranges. Please do not measure the capacitance on wire,
though it can measure, it will cause the big error and damage the meter (if
the wire is not power off or there exists the voltage, capacitance or without
releasing the capacitance completely).
Under range 20nF maybe there is no way to zero adjust when using SMD test clip
(the clip’s capacitance is bigger than 20pF);
Inductance measurement function is used to measure the inductor value, can’t
used to measure the figure of merit of reactive power. It perhaps gets a wrong
reading if measure the inductance value of resistance;
Please do not measure the inductance on line to avoid damaging the meter.
Before measuring, it should release the capacitor completely to avoid damage.

Capacitance measurement
Capacitance measurementCapacitance measurement
Capacitance measurement
Set the function knob to a proper capacitance range;
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

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.

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.

aintenance
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;
