Appendix F Data Scales
The maximum values for volts, amps and power in the PM175
setup and in communications are limited by the voltage and
current scale settings. See Device Options in Chapter 4 on
how to change the voltage scale in your meter.
The following table defines 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.
2
CT Ratio = CT primary current/CT secondary current
3
The default current scale is 2 CT secondary (2.0A with 1A
secondaries and 10.0A with 5A secondaries).
4
Maximum power is rounded to whole kilowatts. With PT=1.0,
it is limited to 9,999,000 W.
