Note:
The measurement of a large capacitance requires a given period of
stabilization of reading.
To avoid damage to the meter, the measurement of a capacitor with
polarities requires much attention to its polarity.
3.2.6 hFE measurement
To avoid any electric shock and/or damage to the meter, do
not attempt a frequency measurement if the voltage is over
36V for DC current or AC current(valid value).
Frequency measurement:
1.
Turn the rotary switch to the position hFE.
2.
Check the transistor is NPN or PNP type, insert the emitter, base and
collector separately to the correct hole, the approximate value will be
displayed on LCD.
3.2.7 Frequency measurement
To avoid any electric shock and/or damage to the meter, do
not attempt a frequency measurement if the voltage is over
250V for DC current or AC current(valid value).
Frequency measurement:
3.
Turn the rotary switch to the position HZ%.
4.
Connect the test leads in black and in red to COM input socket
and Hz input socket respectively.
5.
Use another two ends of the test lead to measure the frequency of
the circuit to be measured.
6.
Read the measured frequency on LCD screen.
3.2.8 Current measurement
Do not attempt a measurement on the current in a circuit, if
when the voltage between the open-circuit voltage and the
ground is over 250V. If the fuse is blown at the moment of
measurement, you are likely to damage the meter or get
yourself hurt.
To avoid any damage to the meter or equipment to be
measured, do not attempt a current measurement unless you
have examined the meter's protective tube. In attempting a
measurement, you should use the correct input sockets,
