Warning
Do the following to avoid electrical shock or fire if a Fluke 43B
common input is connected to more than 42 V peak (30 V rms):
•
Use only test leads and test lead adapters supplied with the
Fluke 43B (or safety-designed equivalents as specified in the
accessory list, see Chapter 2.)
•
Do not use conventional exposed metal banana plug
connectors.
•
Use only one common connection to the Fluke 43B.
•
Remove all test leads that are not in use.
•
The maximum allowable input voltage is 600V. Use test lead
adapters that have a rating of 600V or more.
•
When powering the Fluke 43B, first connect the power
adapter to the outlet before connecting it to the Fluke 43B.
•
Do not insert metal objects into the power adapter connector
of the Fluke 43B.
Warning
In the scope function it is possible to select AC coupling and to
operate time base ranges and amplitude manually. In this case,
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 42 V peak (30 V rms) not
being detected. To guarantee user safety, all signals should first
be measured with DC coupling. This ensures that the full signal
is measured.
