SECTION II
THEORY OF OPERATION
DESCRIPTION OF CONTROLS
This section of the instruction manual describes the functions of all the various control switches, etc.
which are located on the control panel of the Model CB-832. All controls are clearly marked and
logically grouped so that continual reference to the instruction manual should not be necessary after
the operator has become acquainted with the operation of the test set.
Controls input power to the test set. The self-protected switch resets
after an overload, when placed in the OFF position. Displays will
light when the switch is ON.
Protects power output circuit of CB-832 against overloads.
Protects instrumentation and control circuitry against overloads.
Variable autotransformer provides continuous non-stepped output
from a variety of current-rated terminals. Output system is controlled
by a combination of timer STOP MODE and OUTPUT MODE
Switch positions.
Lights whenever output control circuit is energized.
A combination of the COMMON terminal and any one of the three
current-designated terminals provides an output circuit. Refer to
other sections of the text for an explanation of the output
characteristics of these terminals.
NOTE: The current designation of these terminals has no bearing on the actual current output
capability of each. Much higher currents can be achieved depending on test circuit
impedance and duration of the test.
