MEASURING CAPACITANCE
1. Connect the black test lead to the
COM
jack and the red test
lead to the “+” jack. (
NOTE:
The polarity of the lead
connection is positive "+").
2. Connect test leads across the capacitor under measurement and
be sure that the polarity of connection is observed.
NOTE:
1. When checking in-circuit capacitance, be sure that the circuit
has all power removed and all capacitors are fully discharged.
2. The range control mode in capacitance measurement is
auto-ranging.
MEASURING FREQUENCY
1. Connect the black test lead to the
COM
jack and the red test
lead to the “+” jack.
2. Set the function switch to
"Hz/% Duty"
range.
3. Connect the test leads to the circuit to be measured. The range
will change to display the measured frequency with the best
resolution.
When you push the
“HZ/%”
Button, the mode changes to the
duty cycle check mode.
NOTE
：
The input voltage should be between 800mV and 10V rms.ac. If
the voltage is more than 10V rms., reading may be out of the
accuracy range.
