GxT V953-01 User Manual

The Ferret 953 adapts virtually any dual channel labscope or graphing multimeter to display

the parade pattern.

The quality of the ignition waveform depends on the performance of the labscope.

You must be familiar with the operation of the labscope being used with the Ferret 953. Please

Safety Precautions

Read all Instructions before using the device

• Always wear eye protection when testing vehicles. Be extra careful near

batteries and moving parts. Do not lay tools on a battery.

• Battery gas is highly explosive.

a. If a battery explodes ﬂ ush the acid away from persons skin with generous

amounts of water. Follow up with a neutralizing solution of baking soda

and then more water.

Treat clothing, vehicle parts, and equipment similarly. Any acid traces

inside equipment must be removed by generous rinsing. Dry equipment

and place in a warm 50°C (120°F) oven until thoroughly dry.

b. Never use a wrench on the ungrounded battery terminal until the

grounded one has been disconnected. Contact between the vehicle

body metal and the hot terminal can cause sparks to ignite gas or even

weld tools into a battery short circuit.

c. Keep the space around a battery well ventilated.

d. Do not make sparks or allow ﬂ ames near batteries.

• Before working on a vehicle set the brakes and block the wheels. Beware

of automatic parking brake releases.

• Keep your work area well ventilated and free of exhaust. Engine exhaust

contains deadly poisons. Treat Gas Detector exhaust and drain hoses the

same as the vehicle tailpipe. Both give off deadly exhaust fumes.

• Avoid electrical shocks caused by getting close to live ignition wires or

touching the coil TACH terminal. A person’s reaction near a live engine can

be more damaging than the shock.

• Keep spark producing devices at least 0.5m (18”) above the ﬂ oor to reduce

the hazard of igniting gasoline vapor.

• Do not let test leads wind up in a moving fan or pulley. Route leads

away.

• Remove ﬁ nger rings and metal wrist bands. They can short terminals and

become very hot from electric current.
