EKM Metering

Hi every one,
I bought Ekm-OmniMeter v.3 , but I don’t know how to recover the data in case of having no wifi.
Also, if there is a memory, how big is it, how long it takes to be full or does it over read the older data?
Regards,

Dear Jameson,
thank you.

Dear Jameson,
the system we have in saudi arabia is Tiered rate, it is kind of you if you explain how to do it.
best regards.

Sorry, regarding the example above it is
3,000*0.02 + 3,000*0.05 + 350*0.1 = 60+150+35 = 245

Dear sir,
As it is known for all, the electric companies rate there service to their clients on layers while the EKM metering system (cost/kwh) feature either does not allow layering, or I don’t know how to use it.
Could you please take care of such topic.
