3. OPERATION: The meter will read full scale at INF. with cllps,open,

and when the clips are connected together will read zero on the

left. (See Paragraph #6.) To measure resistance, connect the clips

to the component to be tested and read the prope_ Ohms scale. (X 1 or

x 1ooo)

4. IMPORTANT CAUTION: ALWAYS disconnect ALL L£ADS from any electrical

part to be tested on the vehicle. Failure to observe this caution may
