WARNING
Ignition coils produce a very high voltage. To reduce the risk of
electric shock when conducting RPM tests, DO NOT touch the
uninsulated ends of the test probes, the ignition coil, or the coil
terminals when the engine is running.
1. Plug the RED test lead into the "RPM" jack of the tester;
plug the BLACK test lead into the "COM" jack.
2. Place the RED test lead onto the “Tachometer Signal port”
of the vehicle’s ignition system, or onto the negative (-) side
of the ignition coil. Place the BLACK test lead onto a good
chassis ground or the negative (-) terminal of the battery.
NOTE: If your vehicle is equipped with a COP (Coil On Plug)
system and you are using the
setting, make the RED
test lead connection to the negative (-) side of one of the
ignition coils.
3. Set the tester’s Function/Range Selector Switch to the
or
position, as appropriate (see Controls and Indicators,
Items 14 and 15).
4. Press the CYL button, as necessary, until the correct
number of cylinders for the vehicle under test is shown on
the display.
NOTE: Cylinder selection is not applicable to COP (Coil On
Plug) systems.
5. Start the engine and read the results on the display.
L. CON AND DIS RPM MEASUREMENT
NOTE: CON or DIS rpm measurement requires use of an
