is always displayed in Amperes. This default display option is
illustrated below along with an illustration of the status indicator
indicating a temperature-limited condition (i.e. the reverse-video
T character):
To remove the
Ic
and/or temperature display, simply press the left
or right arrow key again.
I
C
S
LOPE
This value sets the
Ic Slope
parameter in Amperes/Kelvin. Note
that for superconducting magnets, the slope value will be
negative since the maximum current density increases with
decreasing temperature.

FFSET
This value sets the
Ic Offset
parameter in Amperes. This value
shifts the entire
Ic
line by a current offset. A higher offset value
will increase the value of
Ic
for a given temperature.
T
MAX
This value is a maximum allowable system temperature as
measured via the Auxiliary Input channel 3 in Kelvin. The Model
430 Programmer will limit entry of the Target Field/Current
Setpoint to a value of zero if the present temperature exceeds
T

. If the Protection Mode is set for “Cont f(T)”, then
