Sorry, I missed that both markings were on the one meter. I can’t explain that. My only guess is that one overrides the other and they forgot to cross the other out.
With your original Schneider meter (that I assume you own and configure) you can choose between four pulse rate settings. With your Elster revenue meter the pulse rate will be fixed by the provider.
Pulses are not an ideal way to monitor usage, the best they can reveal is average power usage over the variable pulse interval. The longer that pulse interval the more blurred it all becomes. If all you want to do is read your revenue meter once per day without going outside to visit it, then they’re pretty effective but if you want to get a precise picture of when loads are coming on/off you really need to be able to interrogate your meter at a fixed time interval.
As an extreme example, if you consider your Schneider’s coarsest setting of 1 pulse per 100kWh that would work out at roughly 1 pulse per month at my house so wouldn’t be much use for determining anything.
