Performs within specifications in less than 3 seconds after power is applied to the transmitter.
Configuration
By digital communication (HART
®
protocol) using the configuration software CONF401, DDCON100 (for
Windows), or HPC301 and HPC401 (for Palm). It can also be configured using DD and FDT/DTM tools, and
can be partially configured through local adjustment.
In order to keep the equipment configuration safe, the LD301 has two kinds of write protection in its memory.
One is via software and the other a hardware mechanism selected by a key with priority over the software.
