1.2 Inspection
When you get a new LCR meter, please check the instrument
and its accessories. If something is damaged or missed,
please contact the store you bought the instrument from for
adjustment or replacement.
1.3 Accessories
LCR digital bridge meter Kelvin test clip (one pair)
SMD test probe IR data line
Upper computer program C External power supply
2. Safety Instructions
Operating environment and condition:
● Elevation
＜
2000 m
● Relative humidity (RH)
≦
80%RH
● Operating temperature 0-40℃
Note: Do not input voltage at the measurement port. When
measuring capacitance, please discharge first then measure,
otherwise, the meter will be damaged.
Storage and maintenance: Do not use alcohol or other
solvents to clean the meter. If it will not be used for long
time, please remove battery and put the meter in a dry and
clean environment.

If

> 0, it means that the measured object is resistant,
if θ
< 0,
it means that that the measured object is capacitive.
Ls: Inductance series connection measurement mode
3.3 Series-parallel Connection Mode Description
This meter has series and parallel measurement modes.
When the capacitance value of the measured object is large
or inductance value is small, use the series mode for more
accurate results. When the capacitance value of the
measured object is small or inductance value is large, use
the parallel mode for more accurate results. This meter can
select the measurement mode automatically according to
the measured object.
