Safely Using the Test Tool
5
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.
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.
Always connect the battery charger first to
the ac outlet before connecting it to the Test
Tool.
Do not connect the ground wire (Figure 1,
item 5) to voltages higher than 42 V peak (30
Vrms) from earth ground.
Do not apply input voltages above the rating
of the instrument. Use caution when using
1:1 test leads because the probe tip voltage
will be directly transmitted to the Test Tool.
Do not use exposed metal BNC or banana
plug connectors.
