Safety

When working with electricity, no instrument can guarantee complete safety.
It is the responsibility of the person who works with the instrument to op-
erate it in a safe way. Maximum security is achieved by selecting the proper
instruments 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
AC
or 60 V
DC
should only
be performed by qualified personnel.
•
Avoid working alone.
•
Observe all indications on the Handyscope HS4 before connecting any wiring
•
Check the probes/test leads for damages. Do
not
use them if they are dam-
aged
•
Take care when measuring at voltages higher than 25 V
AC
or 60 V
DC
.
•
Do not operate the equipment in an explosive atmosphere or in the pres-
ence of flammable gases or fumes.
•
Do not use the equipment if it does not operate properly. Have the equip-
ment inspected by qualified service personal. If necessary, return the equip-
ment to TiePie engineering for service and repair to ensure that safety fea-
tures are maintained.
•
Measuring directly on the
line voltage
can be very dangerous. The
out-
side
of the
BNC connectors
at the Handyscope HS4 are connected with
the
ground
of the computer. Use a good isolation transformer or a differ-
ential probe when measuring at the
line voltage
or at
grounded power
supplies
! A short-circuit current will flow if the
ground
of the Handyscope
HS4 is connected to a positive voltage. This short-circuit current can damage
both the Handyscope HS4 and the computer.
