Important Considerations

•

This instrument must NEVER be connected to powered
equipment/components.

•

It is the user’s responsibility to ensure that any dangerously
charged capacitors are safely discharged before connection
to the unit.

•

To allow the self'protection mechanism to function, always
ensure that the

has completed any analysis before

connecting the test probes to a component.

•

Failure to comply with these warnings may result in personal
injury, damage to the equipment under test, damage to the

and invalidation of the manufacturer's warranty.

•

Avoid rough treatment, hard knocks and extreme
temperatures.

•

This unit is not waterproof.
