Unpacking and Inspecting the Instrument 2-3.
Verify the contents of the shipping package against the checklist in the package. If
any items are missing or damaged, report the problem immediately to your Fluke
representative.
Carefully remove the instrument from its shipping container, saving the packaging
materials if possible. Inspect the rear rubber feet of the instrument. If they are
flush with the bottom of the case, then rotate them 180 degrees so that their
support pads extend slightly below the bottom of the case.
Positioning and Rack Mounting 2-4.
Position the instrument in any location that meets the environmental
specifications. (Refer to Appendix A.) The Y2641 Rack Mounting Kit includes
hardware and instructions to mount one or two instruments (see "Options and
Accessories" in Chapter 1).
Connecting to a Power Source and Grounding 2-5.
You can connect the instrument to an ac power source between 107 to 264V ac
(45 to 65 Hz), to a dc power source between 9 and 16V dc, or to both. Fluke
guarantees equipment specifications only for 50 Hz and 60 Hz operation. Refer to
Figure 2-2 and the descriptions below for making power connections. If you
connect both ac power and dc power to the instrument, the instrument uses ac
power when it exceeds approximately 8 times the value of the dc voltage.
Automatic switchover occurs between ac and dc power without interrupting
instrument operation.
If you connect both ac and dc power to the instrument, the ac and dc ground
connections must be to the same earth ground terminal.
