Capacitance Measurement - Mastech MS8240B Operating Instruction

5.5 Capacitance Measurement

Warning
To avoid damaging meter or device to be measured,
before continuity tests, turn off all circuits to be
tested and discharge all capacitors.
The capacitance measuring range of this meter:
2.000nF, 20.00nF, 200.0nF, 2.000uF and 200.0uF.
Method of measuring capacitance:
1. Rotate switch to the appropriate position.
2. Connect black and red test probe to COM input socket
and V input socket, respectively. (You can also use
the dedicated multifunction test holder to measure
capacitance).
3. Measure the two leads of the capacitor to be tested
with other two ends of test probes and read the
measured value from LCD display.
Note:
When measuring bulk capacitors with this meter,
readings will be stablizee after a few seconds.
When measuring the small capacitor with less than 20nF,
the distributed capacitance (displayed base number)
of the meter and wire should be subtracted.

5.6 Transistor Measurement
Warning
Do not apply any RMS voltage higher than 250V DC
or AC between common end and hFE end.
This prevents electrical shock and/or meter damage.
Method of measuring transistor:
1. Rotate the switch to hFE position.
2. Plug multi-function socket with correct polarity
(the "+" end of multi-function socket is connected with
hFE end, "COM" end is connected with common end).
3. Determine that the transistor is NPN or PNP type,
then insert three pins of transistor, e.b.c, to the
corresponding holes of dedicated multi-functional
socket.
4. Read hFE approximation of transistor to be measured
from LCD display.
