WARNING

Avoid Electrical Shock:

• Make sure that the vehicle to be tested is at a safe potential before making any measurement connections.

• Connect the COM input of the instrument to vehicle ground before clamping the standard SECONDARY PICKUP

(supplied) on the ignition wires. This ground connection is required IN ADDITION TO the normal measurement
ground connections.

• Do not touch ignition coils, coil terminals, and spark plugs while operating. They emit high voltages.

• Do not puncture an ignition wire to connect the instrument, unless specifically instructed by vehicle manufacturer.

• Be sure the ignition is in the OFF position, headlights and other accessories are off, and doors are closed before

disconnecting the battery cables. This also prevents damage to on-board computer systems.

IF the ground of the instrument is connected to a voltage higher than 42 V peak (30 V rms);

• Use only the standard test leads set supplied with the instrument.

• Do not use conventional exposed metal BNC or BANANA PLUG connectors.

• Use only one ground connection to the instrument (GROUND LEAD of the CH A’s shielded test lead).

• Remove all probes and test leads that are not in use.

• Connect the power adapter to the AC outlet before connecting it to the instrument.

Follow the general safety guidelines below;

• Avoid working alone.

• Inspect the test leads for damaged insulation or exposed metal. Check test lead continuity. Replace damaged

leads before use.

• Do not use the instrument if it looks damaged.

• Select the proper function and range for your measurement.

• When using the probes, keep your fingers away from probe contacts.

Keep your fingers behind the finger guards on the probes.
