GxT Ferret 88 Timing Light - Manual (Page 4)

Strobe Light Measurements
The Strobe function on the Ferret 88 does not require the use of the inductive
spark pickup. You can use the strobe function to determine the RPM of any
rotating device.
1. Connect the power leads: RED - positive, BLACK - negative. Push the
Mode Select button to select strobe operation.
2. Point the light beam at a rotating device.
3. Use the trigger button to increase or decrease the rate of the strobe fl ash
4. Begin increasing the fl ash rate of the strobe until you see a stopped motion
view of the rotating device.
5. Read the RPM of the rotating device on the back of the timing light.
Start at the lowest RPM available in the strobe function and increase the rate
until you see a single image that has been “stopped” by the light.
For example, if you are fl ashing the strobe light at a device that has 3 distinct
fan blades, you will see multiple blades stopped by the strobe. Continue
increasing the rate of the strobe until you see just 3 blades. This will be your
correct RPM.
Maintenance & Service
When cleaning the timing light, use a cloth dampened with waterless hand
cleaner. DO NOT use solvents such as acetone and benzene which can be
absorbed by and damage plastics. Promptly remove penetrating oils, gasoline,
and battery acid.
The Inductive Spark Pickup is a plug-in replaceable lead. It can be repaired or
replaced if damaged. Leave the Pickup latch Open when not in use. The
magnetic cores are made of ferrite ceramic and, when kept apart, they are less
likely to break if the pickup is dropped.
There are no user serviceable parts inside the timing light. Contact your tool
dealer or consult other materials packed with the light for repair information.
Electrical Interference
In the event that the unit is subjected to extreme electromagnetic conditions
the display may appear to lock up. Simply disconnect the power lead and
reconnect to reset the unit.
