PM130 PLUS Powermeter Series 159
Appendix F Data Scales
The maximum values for volts, amps and power in the PM130 PLUS 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.

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).

Maximum power is rounded to whole kilowatts. With PT=1.0, it is limited to 9,999,000 W.
