1.2 Operational Safety
The PDL PRO is designed to be used by skilled persons in accordance with safe
methods of work. If the PDL PRO is used in a manner not specified by Socket &
See, the protection provided by it may be impaired.
Inspect the product before using. If any damage is visible; such as cracks in the
casing, damage to any accessories, leads or probes, the unit should not be
used.
Do not operate the PDL PRO with the battery cover off as this will compromise
the insulated safety barrier.
To maintain safety, ensure serviceability and to monitor accuracy of the PDL
PRO the tester should be checked on a checkbox such as the Socket & See
CB400 at regular intervals.
Although fully protected against over voltage up to 440V, the tester should
only be used on 230V systems.
