Care of the oscilloscope
The oscilloscope contains no user-serviceable parts. Repair, servicing and
calibration require specialized test equipment and must only be performed by
Pico Technology or an approved service provider. There may be a charge for these
services unless covered by Pico technology’s two-year warranty.
WARNING
To prevent injury or death, do not use the oscilloscope if it appears to be
damaged in any way, and stop use immediately if you are concerned by
any abnormal operations.
WARNING
To prevent electric shock, do not tamper with or disassemble the
oscilloscope, case parts, connectors or accessories.
WARNING
When cleaning the product, use a soft cloth and a solution of mild soap
or detergent in water. To prevent electric shock, do not allow liquids to
enter the oscilloscope casing, as this will compromise the electronics or
insulation inside.
WARNING
To prevent injury or death, the oscilloscope must not be directly connected
to the mains (line power). To measure mains voltages, use a differential
isolating probe specifically rated for mains use, such as the TA041 listed
on Pico Technology’s website.
CAUTION
Exceeding the overload protection range on any connector can cause
permanent damage to the oscilloscope and other connected equipment.
Grounding
WARNING
The scope’s ground connection through the USB cable is for measurement
purposes only. The oscilloscope does not have a protective safety ground.
