Appendix F Data Scales
The maximum values for volts, amps and power in the PM135 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 and
current scales in your meter.
The following table shows the meter data scales.

1 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 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.
