About the only way to get the Rotating Register (the "Wheel") to spin fast will be to draw a high level of True Power through the Meter - as it measures "Long-Term" true power consumption (more like draw).
If the Rr was a very low number - like Rr=1, then the Rotating Register would spin fast - as compared to the load drawn through it.
On a two-wire 120VAC KWH Meter, with an Rr of 1, and class rating of <200 Amps, the "Wheel" spins like crazy with a 1KW load drawn through it. I mean it spins so fast, the 360° notch mark cannot be seen, as it flashes by with each RPM!
To achieve a faster spin, the Rr will need to be as low as possible. I would expect the Rr of your Meter to be something like 14-7/9, or more. Sound right? You will see this printed somewhere on the meter - most commonly printed on the Dial Registers' faceplate.
Lastly, the way you have connected the 240VAC KWH Meter is not accurate for that meter's rating. It should have 240 VAC conencted through it for proper KWH reads (I'll double verify this in the books if needed!).
Maybe using a Series Motor to spin the "Wheel" would be an option?!?! A setup like typical floor heaters with blower fans is what I am referring to.
If not, then simply spin it with a variable speed Motor - not series with any loads.
Last options are to rewind / reconfigure the Voltage and Current Transformers within the Meters,
or simply draw a gang-load of True Power through the Meters.
Remember, these things respond to True Power Consumption (how much Wattage is drawn over a period of time), not Volt-Amps or Current; so to make them run faster, they need to see larger levels of power.
Let us know what's up and stuff!
