1.2 Precautions
This product has been designed with your safety in mind, but please pay
attention to the following warnings and cautions before use.
Warnings
In order to avoid the danger of electrical shock, it is important that proper
safety measures are taken when working with voltages exceeding 30V AC
rms, 42V AC peak or 60V DC.
Where applicable other safety measures such as the use of protective
gloves, goggles etc. should be employed.
The instrument must only be used by a skilled and competent person who
is familiar with the relevant regulations, the safety risks involved and the
consequent normal safe working practices.
If the test equipment is used in a manner not specified in this user manual,
the protection provided by the equipment could be impaired.
Before each use the instrument and any associated test leads and
accessories should be examined for damage, cracks, cuts or scratches. DO
NOT USE if damaged in any way.
Make sure the instrument and any associated test leads are dry, clean and
free from dust, grease and moisture while in use to avoid the danger from
electric shock due to surface leakage.
Do not use the instrument in AC supply systems with voltages higher than
550 Va.c.
If the removable probe tip caps are not fitted to the probes of the test leads
or the TL180 test probe, their measurement category becomes CAT II
1000V, and they must not be used on CAT III or CAT IV installations to
avoid the risk of shorting high energy circuits and arc flash.
When this unit is used in combination with test leads, the measurement
category of the combination is the lower measurement category of either
this unit or the test leads used. Likewise if test lead accessories such as
crocodile clips are also used, the measurement category will be the lowest
measurement category in that combination.
Do not use if the battery compartment cover is not fitted.
When using test leads / crocodile clips, always keep your fingers behind
the finger guard on the test lead probe or crocodile clip.
Test leads and any test lead accessories must be properly seated and
firmly connected before use.
