AND CONTINUITY

O-4500 OHMS

STE/lCE-R TEST 91

1. Connect RED clip and BLACK clip to the

terminations indicated in the question.

2. Start lest 91, o-4.500 Ohms.

3. Displayed reading is in ohms. Less than 5 ohms

is continuity. If the resistance is over 4.500

ohms, STEACE-R displays .9.9.9.9.

CONTINUITY

(RESISTANCE)

MULTIMETER

1. Set the voltmeter to an ohms scale of about

1,000 ohms.

2. Connect the RED and BLACK leads to the

connections stated in the question.

3. Be sure to read the

correct

scale. Less than 5

ohms indicates continuity. For an open circuit,

the meter should peg full scale (needle all the

way to the left).
