[ GB ] [ GB ] HD208 Minidatalogger Temperature – Temperature/Relative humidity APPLICATIONS % Monitoring of goods (food, drugs, plants, perishable products in general) during transport and storage % Laboratories % Museums and document archives DESCRIPTION The data loggers of the series HD208 are compact instruments for monitoring temperature, relative humidity (RH) and dew point temperature.
Power supply LED (POWER): briefly flashes every 10 seconds to indicate that the instrument is powered. It is steady on if the instrument is connected to the PC. Logging LED (LOG): briefly flashes three times when logging starts and stops, and every 10 seconds during logging. Alarm LED (ALARM): briefly flashes every 10 seconds if any of the measured quantities is in alarm.

PDF REPORT At the end of each logging session, the data logger automatically generates a PDF report, which can then be copied to the PC via the USB port of the instrument. When generating the report, the display of the instrument shows PdF. The report includes the graphs of the detected quantities and information about the logging session: logging start and stop time, logging interval, number of samples acquired, alarm thresholds, minimum, average and maximum of each detected quantity.
In the graphs are shown in gray the areas of alarm (values that exceed the thresholds set). The time required to generate the PDF file depends on the amount of data acquired, and can go from a few seconds (if the amount of data acquired is limited) up to about a minute. Note: the PDF report is generated with the data stored in the Flash memory; the number of samples in the Flash memory may be less than the number of samples stored in the CSV file (please see the memory capacity in the specifications table).
CONNECTION TO THE PC Pull out the protection of the USB output and connect the instrument to the PC by using the cable CP23. If the instrument is not logging, the PC detects it as a simple USB flash drive and appears the list of PDF and CSV files with the reports and the data of the logging sessions. In order to transfer data from the internal memory of the instrument in a database in the PC, use the HD35AP-S application software following the on-line instructions of the software.
INSTALLATION OF THE INSTRUMENT The case of the instrument is provided with a hole on the back to fix it to a support (screw or hook) on the wall. Insert the head of the support in the lower part of the hole (width 10 mm) and lower the instrument so that the head of the support remains wedged in the upper part of the hole (width 6 mm). Make sure that the instrument cannot accidentally come out from the support. Fixing hole BATTERY The instrument uses a 3.
