3.2.5 Capacitance measurement
.&.
To avoid the meter or the ·measured equipment from
·
damage, do not attempt a capacitance measurement
unless the operator has already cut off all power sources
for the circuit to be measured and fully discharged all
high-voltage capacitors. Use the DC voltage position to
determine that all capacitors have been discharqed.
The measuring ranges for the capacitance of this meter are 6.000nF,
60.00nF, 600.0nF, 6.000µF, 60.00µF and 600.0µF,6mF,100mF.
Measurement of capacitance:
1. Turn the rotary switch to the position
-11-.
2. Connect the test leads in black and in red to COM input socket
and
-t
I-input socket respectively.
3. Use another two ends of the test lead to measure the capacitance
of the capacitor to be measured, and capture the measured value
on LCD screen.
Notes:
• The measurement of a large capacitance requires a given period of
stabiliz ation of reading.
• To avoid damage to the meter, the measurement of a capacitor
with polarities requires much attention to its polarity.
3.2.6 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:
1. Turn the rotary switch to the position HZ% , Press "Hz%" to
switch HZ or% function.
2. Connect the test leads in black and in red to COM input socket
and Hz input socket respectively.
3. Use another two ends of the test lead to measure the
frequency of the circuit to be measured.
