Data Scales
The maximum values for volts, amps and power in the EM13X Series
setup and in communications are limited by the voltage and current
scale settings.
The following table shows the meter data scales.

The default voltage scale is 144V. The recommended voltage scale is
120V+20% = 144V for using with external PT's, and 690V+20% =
828V for a direct connection to power line.

CT Ratio = CT primary current/CT secondary current
3
The default current scale is 2  CT secondary (2.0A with 1A secondary
and 10.0A with 5A secondary).
4
Maximum power is rounded to whole kilowatts. With PT=1.0, it is
limited to 9,999,000 W.
