manually for the measurement, press RANGE button to select a proper range. There are six ranges to choose
from: 800.00Ω/8.0000kΩ/80.000kΩ/800.00kΩ/8.0000MΩ/80.000MΩ
Connect the black test lead to "COM" terminal and the read test lead to "VΩ Hz" terminal.

4.7 Capacitance Measurement (CAP)
WANRNING: To avoid damage to the meter or the testing equipments disconnect circuit power and
discharge all high voltage capacitors before measuring capacitance. Use the DC function to confirm that the
capacitor is discharged.
NOTE:
Some capacitors have polarities. In measuring polarities capacitors, touch the red test lead to the positive

polarity and the black test lead to the negative polarity.
In measuring low capacitance, the resistance of the test leads may cause an error in the test results. To avoid

this error, first short the test leads, next press REL△ button. The primary display will be null and the
secondary display displays the resistance of test lead. Measure the to-be tested resistance and the result will
be displayed on the primary display.
Capacitor is capable of storing electric charge. When testing capacitance, only the value on a stable display is the
correct result.
