Yes, of course. Sorry.

However, I was told by a Masterguard technician (did I mention those  
people are incredibly helpful?) that a value called input fault  
voltage actually stores the last transient (and is cleared by reading  
it). So you can store this transient value into min/max values  
maintained by the driver.
