Regulations
General
This measuring device is only to be installed and operated by qualified
personnel and according to the technical data in compliance with the
safety precautions and regulations set forth below. Additionally, the
use of this equipment requires compliance with all legal and safety
regulations pertaining to each specific application. Similar regulations
apply to the use of accessories.
Operating electrical devices implies that parts of the device carry dan-
gerous voltages. Disregarding warning notices may lead to serious
physical injury and material damage.
It can be assumed that safe operation is no longer possible if the de-
vice
•
shows visible damage,
•
has been exposed to unfavourable conditions
(e.g. storage beyond
the permissible climatic limits without adaptation to the ambient climate,
dewing etc.) or
•
has been exposed to major strain during transport
(e.g. been
dropped from some height without visible external damage etc.).
No measurements must be performed on unprotected measuring cir-
cuits.
Qualified Personnel
Are persons familiar with the setting up, installation, starting of and operation
of the device and possess an appropriate qualification required for such ac-
tivities.
Special warnings
•
Use of rubber gloves is a good safety practice even if the equipment is
properly operated and grounded.
•
Safety is the responsibility of the operator.
•
Use extreme caution when using the instrument around energized elec-
trical equipment.
•
Do not attempt to use the ground tester to twist or pry the ground elec-
trode or ground wire away from the equipment being grounded.
•
All metal objects or wires connected to the electrical system should be
assumed to be lethal until tested. Grounding systems are no exception.
