mentioned above.

To minimize the effect of capacitance stored in the test leads,
the test lead should be as short as possible. To measure a
small value of capacitance, use REL mode to remove the
leads capacitance. Remaining voltage, insulated impedance,
& dielectric absorption from the capacitor may cause slight
measurement error.
l
Higher value capacitors will require additional time for
measurement.The 100 F range requires up to 15 seconds.

The measurement range is from 10Hz to 10MHz. To measure
frequency, connect the Meter as follows:
1. Insert the red test lead into theHzV terminal and the black
test lead into the COM terminal.
2. Set the rotary switch to Hz; frequency measurement (Hz) is
default or press Hz % to select Hz measurement mode.
3. Connect the test leads across with the object being measured.
