1. A device comprising:
an enclosure having a cylindrical bore;
a piston located within the cylindrical bore, the piston having a first end and a second end;
a motor controller within the enclosure, the motor controller responsive to a measured magnitude of electrical current flowing through a motor to selectively activate a first pressure indicator corresponding to the measured magnitude of the electrical current being at least as great as a first threshold magnitude and to selectively activate a second pressure indicator corresponding to the measured magnitude being as great as a second threshold magnitude; and
at least one display device responsive to the first pressure indicator and to the second pressure indicator to display a visual indication of a pressure corresponding to the measured magnitude of the electrical current.
