FREQUENCY MEASUREMENT
1) Set the function switch to the Hz position.
2) Insert the black test lead banana plug into the negative COM jack.
3) Insert the red test lead banana plug into the positive VHz% jack.
4) Touch the test probe tips to the circuit under test.
5) Read the frequency in the display. The digital reading will indicate the
proper decimal point, symbols (Hz, kHz, MHz) and value.
