Power Supply 43B Users Manual

Safety Information: Read First

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.
