When Installing and Removing the MR8904 into and from the Memory
HiCorder
• To avoid electric shock accident, before removing or replacing an MR8904, confirm
that the instrument is turned off and that the power cord and connection cables are
disconnected. The mounting screws must be firmly tightened or the MR8904 and
the Memory HiCorder may not perform to specifications, or may even fail.
• To avoid the danger of electric shock, never operate the Memory HiCorder with an
input module removed. To use the Memory HiCorder after removing an input mod-
ule, install a blank panel over the opening of the removed module.
Blank panel
Measurements made without a blank panel installed may fail to meet specifications
because of temperature instability within the input modules.
