IMPORTANT
To maintain accuracy of the meter, replace the discharged
battery immediately when the battery symbol appears on
the meter display.
Avoid measuring error from outside interference: keep the meter
away from spark plug or coil wires.
Avoid damaging the meter when testing voltage: disconnect the
test leads from the test points before changing functions.
Do not exceed the limits shown in the table below:
