This document includes the following questions:

- On an XL3xx, when I navigate from one toroid to another using the « increment » button, there is one toroid which is skipped. I cannot access the measurements for this toroid.

- I did the following test : I disconnected one toroid from the XL3xx or the XML3xx. But I did not see the message “tor” in the XL3xx display, which is supposed to appear and warn me that one toroid is disconnected. Why is that?

- How can I acknowledge intermittent faults on the XL3xx ?

- Why do the XL3xx or XML3xx display « .. » instead of showing the measurements per feeder? In the manual, it is mentioned that this means “measurement impossible, the CPI is a fault and the fault is not one the channel selected”. What does it mean exactly?

- On XL3xx or XML3xx, what is the meaning of “A3x” (A31, A32….)?

- In my system, the Insulation Monitoring Device is indicating a fault. But none of the XL3xx locator indicates a fault. What is the explanation?
