I stupidly didnt take a snap of the instructions, was on a flying visit. The brand suggests its for or from a caravan oddly...
I took these other pictures though and could not identify a trip nor the reason behind there being both a digital and analogue meter. This combined with the mystery timer has us very confused.

It's a solid-state two-rate meter and a Sangam0 80A Timeswitch, used, for example, for Economy 7 tariff. The grey wire linking the timeswitch to the meter switches the rates on the meter.
