Prepay meters

[Johnygas]

New to this and know it's prob covered elsewhere but came across this meter today and couldn't work out how to do gas rate. Holding down A gets you into menu keep pressing A just takes you through payment and tarriffs nothing else. B just beeps at ya. Could use some help please.

They are a pain. Be careful to be careful. Pressing at wrong time gives wrong result, and you have to wait to start again.

I find this easier than TB: Have appliance running. Press A, then B straight away and start the 2 mins. The index will come up but may be a short delay. Record index. At 2 minutes TURN OFF ECV. You can then press A and B again to get new index and calculate .

TBH, my current job for the last year does not require me to gas rate appliance,so I hope I have that right.
