Connecting Method of Instruments and Handling Instructions
1. Engine tachometer
(1)
In the case of a tachometer in which the pick-up is made from the primary circuit and there is
no
3-cylinder range, carry out the measurement using the 6-cylinder range. And multiply the reading
by
2.
This product is the actual revolutional speed of the 3-cylinder engine.
(2)
In the case of a tachometer in which the pulses flowing through the resistive cord of the cylinder
No.1 are sensed, the reading can be read directly regardless of
the number of cylinders.
2.
The power supply for the tachometer, timing light and other instruments should be connected to the
battery terminal.
3. Never disconnect the battery terminals while the
engine is running.
(Failure to observe this caution will cause abnormal pulses to apply to ihe transistors, even leading to
damage of the transistors and other electronic meters, etc.)
4.
Care must be exercised to ensure that no water gets to each electric part during the cleaning.
5.
Make sure that the CO meter is adjusted and calibrated accurately before it is put into use.
