MS8910A
Smart SMD Tester
USER'S MANUAL
1. Introduction
Thank you for purchasing a MS8910A smart
SMD tester.
The MS8910A smart
SMD tester is a professional
instrument for measuring inductance, capacitance and
resistance. It has many features, such as automatic
identification, automatic measurement range, high
measurement accuracy and speed, wide measuring
range and so on.
An ordinary multimeter only provides DC mode for
resistance measurement, while the MS8910A provides
both AC and DC measurement modes. A variety of test
frequencies up to 100Khz can be provided for inductance,
capacitance and resistance in AC mode to meet the
actual needs better.
Correct usage can ensure that the instrument will work
precisely for a long time. Please read the instructions
carefully before using and operate the instrument strictly
in accordance with the instructions .

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.
2. Safety instructions:
Operating environment and condition:
• Elevation <2000
m
• Relative humidity (RH)
≦
80%RH
• Operating temperature 0 – 40°C
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
θ
> 0, it means that the measured object is resistant,
if
θ
< 0, it means that that the measured object is
capacitive.
3.2 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. When the measured
impedance in 10K
Ω
below is set to SER(Series mode),
when the measured impedance in 10K
Ω
above set to PAL
(parallel mode).
4. Functional characteristics description:
1. 6000 count
2. LC automatic range measurement
3. R analytical measurement
4. DCR mode of resistance measurement
5. D/Q display:The automatic selection for the
C+D/L+Q/R+Q
6. Measuring voltage : 0.5VRMS/0.1VRMS
7. The test frequency AC mode :100/120/1k/10k/100k
8. Battery electric power display : Long time not to operate
the power off automatically
9. See table 1-3 for measurement accuracy and scope
Remarks: This accuracy is the measurement
standard. In DUT jack, the meter-specific probe
should be used if required. Measurement with probe
may be influenced by external environment. To
avoid inaccurate measurements, please keep away
from strong magnetic sources.
