1. Connect the Clamp to a spark plug wire

with the arrow on the Clamp pointing

to the spark plug. Position the Clamp

as far away from the distributor and

the exhaust manifold as possible.

2. Connect the black Lead of the

clamp to the “COM” Jack of the

Multimeter/Tachometer and the red

Lead to the “ ” Jack.

3. Set the Function/Range switch to

the vehicle’s number of cylinders.

4. Read the value on the display. The

distance between the spark plug and

the Clamp of the unit must be less than

4" (10cm) during the test. Multiply the

reading by 10 to get the actual RPM.

Note: If no reading is received, unhook the

clamp, turn it over and reconnect.
