2. Connect the red test lead to the

jack

and the

black test lead to the COM jack.

3. Connect the red test lead to the test point and the

black lead to the common buss of the logic

circuit.

4. A “

Ⴃ

” on the display indicates TTL logic high and

a “

Ⴍ

” indicates a TTL logic low. Both indicators

are on when the point of measurement is

toggling high and low.
