The Lascar EL-USB-4 current loop data logger can measure and store up to 32,000 readings over a 4 to 20mA DC measurement range. The unit is simply plugged into the USB port of a PC to download the data. Using the included, purpose designed software the data logger may be set up by changing the logger name, logging rate, high and low alarms and start date and time. Also, the software can be used to analyse the downloaded data, displaying powerful interactive graphs and enabling the data to be printed or exported. Measurements are taken via the included set of crocodile clip terminated test leads which attach to the data logger via a pair of screw terminals housed in the unit cap.
