PROGRAMMING USING LOCAL
ADJUSTMENT
The Magnetic Tool
Smar's magnetic tool is the second man machine interface. It comprises the advantage of the powerful
HHT and the convenience of the magnetic tool.
If the transmitter is fitted with a display, and configured for Complete Local Adjustment (using the
internal jumper), the magnetic tool is almost as powerful as the HHT. It eliminates the need for an HHT
in most basic applications.
If the transmitter is not fitted with a display, or is configured for Simple Local Adjustment (using the
internal jumper) the adjustment capability is reduced to ranging.
To select the function mode of the magnetic switches configures the jumpers located at the top of the
main circuit board as indicated in Table 4.1.
