ZERO

button again the meter, Then

repeat the measurement and use the second reading.

3.7 FREQUENCY MEASUREMENTS

1. Set function selector to Hz position. AUTO mode is on, range is automatically selected.
2. Plug black test lead into COM plug. Plug red test lead into Hz



F plug.

3. Connect test leads across desired measuring points. Make sure that peak of frequency signal does not exceed 500 V DC or

AC.

4. Switch meter to

OFF

to conserve power.
