Rotating Default Display (Only on Models With LCD)
Extra Details for Displaying Metering Values on the Rotating Default
Display
Table 7.8 lists all the available metering values that rotate on the default
display, subject to the number of available display points. These values
correspond to the primary metering values available via the METER
command (MET [Instantaneous], MET X [Extended Instantaneous], MET D
[Demand], and MET E [Energy]; see Section 10: Serial Port Communications
and Commands for serial port commands).
Note in Table 7.8 that many of the magnitude values are listed with three
digits behind the decimal point. For example, the first value in Table 7.8 is
shown generically as in this example:
Magnitudes less than 10 display with three digits behind the decimal point:
Magnitudes greater than or equal to 10 display with two or fewer digits behind
the decimal point:
