Putting into Service
To learn how to install, access the front panel, power on, do a self test, and
power off the oscilloscope, do the following procedures:
To properly install and power on the oscilloscope, do the following steps:
1. Be sure you have the appropriate operating environment. Specifications for
temperature, relative humidity, altitude, vibrations, and emissions are
included in the TDS 684A, TDS 744A, & TDS 784A Performance Verifica-
tion and Specifications manual (Tektronix part number 070-8990-xx).
2. Leave space for cooling. Do this by verifying that the air intake and exhaust
holes on the sides of the cabinet (where the fan operates) are free of any
airflow obstructions. Leave at least 5.1 cm (2 inches) free on each side.
WARNING. To avoid electrical shock, be sure that the power cord is disconnected
before checking the fuse.
3. Check the fuse to be sure it is the proper type and rating (see Figure 1–1).
You can use either of two fuses. Each fuse requires its own cap (see
Table
1–2). The oscilloscope is shipped with the UL approved fuse installed.
4. Check that you have the proper electrical connections. The oscilloscope
requires 90 to 250 VAC
RMS
, continuous range, 45 Hz to 440 Hz, and may
require up to 300 W.
5. Connect the proper power cord from the rear-panel power connector (see
Figure 1–1) to the power system.
