The CMD records time-stamped relative humidity (RH) and Temperature measurements in nonvolatile memory. Logging parameters are set from our host computer running DH Tech CMD software. The logger is then started using the host computer. The logger updates displayed measurements every five seconds. The logging interval is selectable from one second to nine hours. Data in the LCD logger can then be offloaded to our DH Tech computers.
