Fluke 123 User Manual page 13

Warning
Should this test tool be used with AC
coupling selected, or manual operation of
amplitude or time base ranges, the measuring
results displayed on the screen may not be
representative of the total signal. This can
result in the presence of dangerous voltages
of more than 42V peak (30V rms), not being
detected. To guarantee user safety, all signals
should first be measured with DC coupling
selected and in fully automatic mode. This
ensures that the full signal content is
measured.
Warning
To avoid electrical shock or fire:
• Use only the power supply, Model PM8907
(Battery Charger / Power Adapter).
• Before use check that the selected/indicated
voltage range on the PM8907 matches the
local line power voltage and frequency.
• For the PM8907/808 universal Battery
Charger/Power Adapter use only line cords
that comply with the local safety regulations.
Safely Using the Test Tool
Note
To accommodate connection to various line
power sockets, the PM8907/808 universal
Battery Charger / Power Adapter is equipped with
a male plug that must be connected to a line cord
appropriate for local use. Since the adapter is
isolated, the line cord does not need to be
equipped with a terminal for connection to
protective ground. Since line cords with a
protective grounding terminal are more commonly
available you might consider using these anyhow.
Warning
To avoid electrical shock or fire if a Test Tool
input is connected to more than 42 V peak (30
Vrms) or on circuits of more than 4800 VA:
• Use only insulated voltage probes, test leads
and adapters supplied with the Test Tool, or
indicated as suitable for the Fluke 123/124
Test Tool.
• Before use, inspect voltage probes, test leads
and accessories for mechanical damage and
replace when damaged.
• Remove all probes, test leads and
accessories that are not in use.
