Note: The reading on the display is given only for a 4-stroke
1-cylinder engine. If the engine under test is a 4-stroke multi-
cylinder engine, you should divide the reading by the number of
cylinders.
Reading's stability will decrease if the rotation speed of the
engine is too low.
Battery Replacement
When the symbol "
" appears on the display, it shows that
the battery should be replaced. To replace the battery, remove
the screws on the case, replace the exhausted battery with new
battery of the same type, reinstall the cover and the screws.
Fuse Replacement
Fuse rarely needs replacement and is blown almost always as a
result of operator's error.
This meter uses a fuse: F 10A L 250V and a fuse: F 500mA L 250V.
To replace the fuse, remove the screws on the case, replace the
damaged fuse with new fuse with the specified ratings, reinstall
the cover and the screws.
