1. Turn ON the unit by depressing POSITION key.
2. Select the POSITION number applicable to the engine to be monitored,
referring to the measuring position chart.
3. Depress the POSITION kea as many times as needed until the selected
POSITION numper appears on the display. With the engine running, hold the
unit so that the sensor end is at an appropriate distance (1cm-50cm) from
the active ignition cable (or on a multiple cylinder engine, from the spot
where all the ignition cables are clustered). "Appropriate monitoring
distance" varies with the signal strength and the type of engines being
monitored; it is established when the rpm readings appearing on the LCD
have become stabilized within a ±10 ~ ±15% rpm range. The engine's rpm
readings will continue to appear at 0.5 sec intervals as long as the unit is held
at the proper monitoring distance (CAUTION: Do not allow the unit to touch
any active ignition cable or the unit's failure may result.)
4. Move the unit away from the running engine or stop the engine, and the
POSITION number will appear on the LCD. The unit will automatically turn
OFF in one minute thereafter.
(2) Antenna lead method (Fig.2)
1. Attach the antenna lead to the unit as illustrated.
2. Get the unit ready for use, following steps (1) 1-3.
3. Connect the antenna lead to the ignition cable using the clip, as shown. On a
multi cylinder engine, attach the antenna lead clip to one of the ignition
cables where all of them are clustered.
F. Notes and Cautions
1. Use P21:42 when 4-stroke 1-cylinder engine that sparks at spark plug every revolution is monitored.
2. Some engines employ „double spark" ignition method where the number of spark per revolution is double that of the ordinary engines. Since rpm readings are given based on
the count of spark-generated electric pulses, this means that the rpm readings displayed represent two times the actual, correct readings. To obtain direct rpm readings on a
double-spark ignition engine, select the POSITION number by doubling the number of cylinders of the engine: For example, the POSITION number to select for a double-spark
ignition, 2-stroke 1 cylinder, or 4-stroke 2 cylinder engine should be P 22:44 instead of P 21:42.
3. Very rarely, strange figures or symbols happen to appear on the LCD. This condition does not represent the unit's failure. If this has occurred, depress RESET key: the figure
8888:88 will temporarily appear and the POSITION number P 21:24 will follow, indicating that the unit is in normal working condition.
4. When the antenna lead is used, be sure to keep it free from contact with metallic surfaces to avoid possible errors in rpm readings.
5. Keep this unit away from strong physical shocks.
6. Never touch the inside circuit to prevent any unnecessary trouble or malfunction..
