2.0 Calibration
2.1 Operator Set Up
MagneCal^™, the Sentinel’s sophisticated calibration software,
uses a microprocessor-based user interface, which provides
the operator unmatched flexibility and programmability
for a variety of level control applications. These features are
built into the controller and are entered via three tactile-
feedback keys (UP arrow, DOWN arrow, and
ENT ^ENT ) located on the amplifier circuit board. In addi-
tion, a 4-digit LED displays the operating parameters and
values. The keys and their functions are shown below.
Upon power up, the LED will display the following mes-
sage: Magnetrol Int’l followed by a series of walk-
ing M’s (multi-point) or S’s (single point), based on the
calibration configuration selected. This is the normal
RUN mode.
UP/RAISE: Use to scroll up through menu selections, or
raise numeric values. There are three speeds for scrolling
numeric values. Ramp speed is increased by continuously
depressing the UP arrow key. To decrease speed as the
desired value is approached, release the UP arrow key
and unit will revert to the slowest ramp speed.
DOWN/LOWER: Use to scroll down through menu selec-
tions or lower numeric values. There are three speeds for
scrolling numeric values. Ramp speed is increased by
continuously depressing the DOWN arrow key. To
decrease speed as the desired value is approached, release
the DOWN arrow key and the unit will revert to
slowest ramp speed.
ENT ENTER: Use to select displayed value and to continue to
the next menu selection. Complete menu layouts are
provided to show the user-selectable parameters.
NOTE: The unit will automatically time out and revert to the RUN mode
after 60 seconds of no key strokes. Any information already
entered is secure, and the calibration may be safely resumed
at any time.
