Accessories
Calibration certificate from the manufacturer - Comet and battery are included in delivery. For basic use it is necessary to order at minimum a COM adapter or USB adapter for communication with computer, optionally a start/stop magnet, if needed to control logging the other way than directly from computer.
Anytime it is possible to download free basic program for Windows. Program enables to control all logger functions and viewing and printing of record in numerical and simple graphic format. It is possible to export logged values to dbf or txt formats for further analysis.
