The HD32MT.1 is a data logger capable of capturing and logging the values measured by a series of sensors connected to its inputs. The data logger is completely programmable by the user and is therefore very versatile. The application software, supplied with the instrument, features simple and intuitive programming using graphic interfaces, without the need to lear a programming language.
The values recorded by the instrument are easily transferred to a PC. The data logger can be configured to memorize the instant value, the minimum value, the maximum value, the average value and the standard deviation of the measurements. For measurements that require the counting of pulses, the total counted pulses can be stored. Different acquisition/recording intervals can be programmed per each input. Each recording includes acquisition date and time The data logger has a “flash” internal memory arranged in circular mode: when the memory is full the new data overwrite the older ones. The number of storable measurements depends on the number of sensors employed, on the type of measurement to be stored and on the fact that the sensors are acquired all at the same time or at different instants. For example, with 8 sensors captured at the same time, 100,000 records can be stored, each one composed of 8 instantaneous measurements. Data can also be directly recorded to a removable SD -type memory card with a capacity of 4 GB . The use of a memory card allows extending the memory capacity of the instrument, without loosing data when the memory is full.
Three data logger versions are available, depending on the communication with the PC
