16 Start a timer and simultaneously move the
control handle all the way to the left or right.
Note how long it takes to reach the maximum
voltage recorded in step 14. This is the
ramp rate.
17 Set the ramp rate: Turn the trimpot to obtain
a 5 second ramp speed. Turn the trimpot
clockwise to increase the time or
counterclockwise to decrease the time.

battery voltage is above
12V DC and the alternator
is operating properly with
13.6 to 14.5V DC output.
Electrocution hazard. Contact
with electrically charged circuits
may result in death or serious
injury. Remove all rings, watches
and other jewelry.
1 Check the battery condition with a volt meter.
The reading should be 12V DC or more to
accurately adjust the controller.
