Please advise

I got work to install prepaid meter ,only on the point of supply.the property has existing COC from the point of control and consumption (DB)
I have been instructed not to remove the old conventional meter. I have installed a meter only .no interference on the point of control and consumption.


Do i issue a full COC or I issue an Abridged COC ?What test do I have to do. in order to issue a COC?

thanks
