Applications : |
| This standalone data logger measures and stores up to 32,000 current loop readings over a 4-20mA
measurement range. The user can easily set up the logging rate and start time, and download the stored data
by plugging the data logger into a PC's USB port and running the purpose designed software under Windows
2000, XP, Vista & 7. The data can then be graphed, printed and exported to other applications. The data logger
is supplied complete with a long-life lithium battery. Correct functioning of the unit is indicated by a flashing
red and green LED. The data logger features a pair of screw terminals and is supplied complete with a set
of measurement leads terminating in crocodile clips. |
