maximum range, the instrument with higher range
shall be selected.
Before measuring the in-circuit capacitance, the power
supply of the tested circuit must be cut off and all
capacitors must be fully discharged.
When measuring the polar capacitance, the red probe
is connected to the positive terminal of the capacitance.
When measuring capacitance above 100µF, it may take
several seconds for the reading to become stable,
which is normal for large capacitance measurement.
3.9 Frequency and duty ratio measurement
1. Insert the red probe into the " INPUT " terminal and the black probe into
the " COM " terminal;
2. Set the function range switch to the position, and tap the " SEL "
button to switch to display the frequency or duty ratio of the
measured signal.
3. Connect the probes to both ends of the power supply or load for
measurement.
4. Read the frequency or duty ratio of the measured signal.
3.10 Temperature measurement
1. Set the function range switch to the " ℃℉ " position. At this time, the
LCD displays the current ambient temperature. Tap the " SEL " button
to switch the temperature unit between ℃ or ℉ .
2. When thermocouple is required to measure temperature, insert the
red probe of K-type thermocouple into the " INPUT " terminal and the
black probe into the " COM " terminal, and use the thermocouple
probes to contact the measured object or area for measurement.
