Safety Notes
If the SafeTest 99 is used in a manner not specified by these operating
instructions, then the protection provided may be impaired.
Only accessories recommended or approved by the manufacturer should be used
with the SafeTest 99.
Do not connect the SafeTest 99 to electrical circuits with nominal voltage greater
than CAT II 300 V AC/DC.
Do not touch test probes beyond the hand barrier on the test probe.
The SafeTest 99 may apply high voltage or mains power to the appliance under
test. Do not touch conductive parts of the appliance while tests are active.
Do not open the SafeTest 99, no user serviceable parts
Do not operate the SafeTest 99 in an explosive gas or dust environment.
The SafeTest 99 and all associated cables and leads must be checked for signs of
damage before equipment is operated. Do not use if there are signs of damage.
Where safe operation of the SafeTest 99 is no longer possible it should be
immediately shut down and secured to prevent accidental operation
It must be assumed that safe operation is no longer possible:
•if the instrument or leads show visible signs of damage or
•the instrument does not function or
•after long periods of storage under adverse environmental conditions.
To verify the correct operation of the unit, perform test functions using a known
appliance or checkbox or return the unit to an approved agent for service.
