PicoScope 4225A and 4425A automotive oscilloscopes and accessories
ACCESSORIES
Do not exceed the voltage rating marked on any accessory. If an accessory is not marked with a
voltage rating on either the connector, cable, or body, or if a protective finger guard is removed, do
not exceed the safe voltage limits listed above.
Never exceed the maximum voltage marked on a CAT-rated accessory, whether or not the
accessory is being used for utility power or high-energy measurements.
When connecting one or multiple accessories and an instrument channel together, the lowest
voltage rating in an interconnected set of accessories applies to that channel.
To avoid causing permanent damage to the instrument and other connected equipment, do not
exceed the voltage protection rating on any cable, connector, or accessory.
Uninsulated HT pickups are designed to clip around double-insulated HT leads only – they are
not designed for direct connection to a hazardous live voltage. To prevent injury or death, switch
off the engine and secure against restart. Clean and inspect the HT lead for damage to insulation
and fit only to undamaged double-insulated leads. Ensure that test leads are safely clear of hot or
rotating parts. You can now restart the engine for the test duration.
Pico accessories for measuring physical properties such as resistance, pressure, temperature,
and ultrasonic signals are not designed to be connected to any voltage source.
To prevent fire, overheating, or possible damage, do not connect any temperature, ultrasonic,
resistance, or pressure sensors to an electrical node unless you have first confirmed that the node
is de-energized.
PicoBNC+ accessories are designed for use with Pico Technology PicoBNC+ automotive
oscilloscopes only.
To avoid possible damage or inaccurate readings, do not attempt to connect PicoBNC+
accessories to other equipment.
