Multiply the displayed
reading times ten to get actual
RPM.
Getting Started
Insert the inductive pick-up con-
necting terminal into the meter.

slope.
The illustration for a mixture con-
trol solenoid is shown with the
metering rod in the closed posi-
tion.
In most applications, the negative
(-1
slope is assigned to display the
percentage of time the plunger is
in the closed position (low duty
cycle) during one duty cycle. The
positive
(
+
slope is assigned to
display the percentage of time the
plunger is in the open position.
Refer to the manufacturer's speci-
fications to verify slope assigned
to position for each component.
