1.ACOperation
This is "normal" operation for the Model 4077.
A 4077 can operate from a line voltage of either 90-135 or 180-270
V-AC (47-63 Hz; 35 W maximum). The VOLTAGE SELECTOR
SWITCH is located on the rear panel (see Fig. 2(a)).
If you change the voltage-level setting, YOU MUST ALSO
CHANGE THE 4077'S BUSS FUSE (again, see Fig. 2.(a)): nominal
110 V-AC takes a 0.5-amp fuse; nominal 220 V-AC takes a 0.25-
amp fuse.
To change the fuse after changing the voltage setting—or after the
existing fuse has "blown" for some reason—use a screwdriver to
turn the fuse slot counterclockwise, and the fuse will spring out.
IN THE EVENT OF AN APPARENT POWER-SUPPLY FAILURE,
FIRST CHECK THE FUSE. WHEN REPLACING A "BLOWN"
FUSE, ALWAYS INVESTIGATE THE CAUSE OF OVERLOAD
BEFORE REACTIVATING THE INSTRUMENT.
2.b Powerup
2.4
---------- PLEASE NOTE ----------
EVERY TIME YOU POWERUP YOUR MODEL4077, ALLOW A
NOMINAL 15 SECONDS FOR VALID DATA AND SETUP
VALUES TO BE ESTABLISHED.
ALSO NOTE: Since setup entries are automatically saved to
nonvolatile memory, your 4077 will always powerup to the
same setup and display configuration that existed when it was
last powered down.
---------- IMPORTANT ----------
Before powering up your 4077, make sure that the VOLTAGE
SELECTOR SWITCH is set to the proper nominal AC line
voltage (110 or 220).
