Smar™s SD1 Magnetic Tool is the second man-machine interface used to make local adjustments in the Smar™s transmitters and converters. It comprises the advantage of the powerful HHT and the convenience of the "good-old" screwdriver.
The instruments have, under the identification plate, holes for two magnetic switches activated by the magnetic tool. If the transmitter or converter are fitted with a display, and configured for Complete Local Adjustment, the magnetic tool is almost as powerful as the HHT. It eliminates the need for an HHT in most basic applications.
