The central unit can work on-line when connected to a computer or independently for set-up, calibrating and storing data in e.g. the field. Eight pH/mV/Ion/oxygen inputs and eight °C inputs permit to perform all functions simultaneously. Collecting stored data and display are controlled through any computer via a single USB connection.
A graphical display will guide the user when the central unit is not connected to a computer. It only permits to set-up, calibrate and start/stop storing data in the internal memory. Connecting the central unit to a computer will automatically disable the display.
All necessary GLP-procedures are on board. The software package supplied with the D130 is specially designed to control, collect and store data. Runs under Windows 2000 or higher. All channels are processed at the same time, each in its own window. Data is collected on-line with a programmable interval determined by the program (4 s … 24 h) or by the internal clock of the unit when operating independently.
Stores up to 32000 values including temperature, time and date in the internal memory when working independently. An unlimited number of values can be stored when operated through a computer.
Documented printouts will show file name, date and time, name of the operator, name of the company, name of the division, optional notes by the operator.
Password protection prevents any unauthorized access to the instrument.
