Safety - TiePie Handyscope HS3 User Manual

Safety

When working with electricity, no instrument can guaran-
tee complete safety. It is the responsibility of the person
who works with the instrument to operate it in a safe way.
Maximum security is achieved by selecting the proper in-
struments and following safe working procedures. Safe
working tips are given below:
Always work according (local) regulations.
Work on installations with voltages higher than 25 V
60 V should only be performed by qualified personnel.
DC
Avoid working alone.
Observe all indications on the Handyscope HS3 before con-
necting any wiring
Check the probes/test leads for damages. Do not use them
if they are damaged
Take care when measuring at voltages higher than 25 V
60 V .
DC
Do not operate the equipment in an explosive atmosphere or
in the presence of flammable gases or fumes.
Do not use the equipment if it does not operate properly.
Have the equipment inspected by qualified service personal.
If necessary, return the equipment to TiePie engineering for
service and repair to ensure that safety features are main-
tained.
Measuring directly on the line voltage can be very danger-
ous. The outside of the BNC connectors at the Handy-
scope HS3 are connected with the ground of the computer.
Use a good isolation transformer or a differential probe when
measuring at the line voltage or at grounded power sup-
plies! A short-circuit current will flow if the ground of the
Handyscope HS3 is connected to a positive voltage. This
short-circuit current can damage both the Handyscope HS3
and the computer.
