V rms, depending on the power range setting inside the
instrument, as ordered with the 2212, with any frequency
from 48 Hz to 440 Hz.

Connect the proper power cord from the rear-panel
power connector to the power system.
• Step 3: Check the fuse (located on the rear panel), to be
sure it is of the proper type and rating.
Use the following procedure to check that the proper fuse is
installed or to install a replacement fuse.
