Mastech MS8910A User Manual

MS8910A
1. Introduction
Smart SMD Tester
Thank you for purchasing a MS8910A smart SMD tester.
USER'S MANUAL 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 .

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.

AUTO: This character showing on the LCD means that 3.2 Series-parallel connection mode description
the tester works in LCR automatic range mode
This meter has series and parallel measurement modes.
PAL: parallel connection measurement mode
When the capacitance value of the measured object is
SER: seriesl connection measurement mode
large or inductance value is small, use the series mode
C: Capacitance series/parallel connection measurement
for more accurate results. When the capacitance value of
mode
the measured object is small or inductance value is large,
L: Inductance series/parallel connection measurement
use the parallel mode for more accurate results. This
mode
meter can select the measurement mode automatically
R: Resistance series /parallel connection measurement
according to the measured object. When the measured
mode
impedance in 10KΩ below is set to SER(Series mode),
DCR: Resistance DC measurement mode
when the measured impedance in 10K Ωabove set to PAL
D: Wastage factor
(parallel mode).
Q: Quality factor

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.
