The Chauvin Arnoux CA6543 Megohmmeter Digital with RS 232 and Software operates at an extremely wide range of voltage from 50V to 1kV. Its resistance ranges from 0.01Ω to 400kΩ.
Charmin Arnoux has ensured that the CA6541 comes ready with a number of helpful measurement aids and tools, including the onboard graph plotter. Thanks to the sizeable internal memory on the device, you can begin a time-controlled test and this digital megohmmeter will automatically store insulation values for you to plot an R(t) graph with.
When it comes to plotting your R(t) graph, you could do it by hand, but the faster way would be to use the specifically-designed PC software included in the box. You can use this software to store the data memorised by the CA6541 and then plot insulation progression graphs on your computer.
Even better than that, the Chauvin Arnoux CA6543 Megohmmeter Digital with RS 232 and Software also has a RS232 interface to enable serial link. This will allow you to control the CA6541 faultlessly from your computer through the software package.
The Chauvin Arnoux CA6543 Megohmmeter Digital with RS 232 and Software is stored in a durable hard case that is IP54 watertight, so you can still take those all-important measurements even in the worst conditions. The hard case also has a carry case connected where you can store all of the testing accessories that you need to bring along.
This digital megohmmeter uses a large digital LCD screen that has ample backlighting, so you will be able to view measurements easily. There is also a logarithmic bar graph display that takes the measurements you store and converts them into analogue format alongside the digital values.
