Schlumberger A6A1 Four rate meter

Rare Schlumberger 4 rate watthour meter, ex EDF France.
I got hold of this meter through one of the big auction sites.
It is a CT meter but it will work as a direct connected meter provided the load per element does not exceed 10 Amps.
Readings in the latter case have to be divided by 20 as the registers read true values for a 100 / 5 Amps CT set up.
