371B Setup and Initialization
Perform the following to setup and initialize the 371B before making any
performance checks or adjustments.
1. Check that the 371B is set for the proper power source and that a suitable
power cord has been attached.
2. Remove the 371B cabinet panels to gain access to internal adjustments and
test points.
For instructions on cabinet panel removal, refer the the description under the
heading “Component Removal and Replacement” in Chapter 4: Maintenance
of this manual.
Use extreme care when operating the 371B with the covers removed,
due to the line voltage, high-voltage, and high-current levels present.
3. Connect the 371B to a suitable power source.
4. Press the POWER button and allow at least 20 minutes warm-up before
proceeding.
During the power-up process, the 371B sets front panel controls to initial
(default) settings. At the beginning of most procedures, you will be instructed to
“initialize the 371B.” This means that you are to have first saved the power up
settings in memory before you can “recall” them in order to initialize the 371B.
Perform the following procedure to save the power-up default settings.
1. Press the setup SAVE button to store the default settings in memory
location 1.
2. Check that the SAVE COMPLETE message is displayed.
These default settings together with the manual initialization settings are
used as the initial control settings throughout the procedure, except as noted
otherwise.
