example, if the cumulative power value is 1278.56 kWh when Pr. 891 = "2", the PU/DU display is
12.78 (display in 100 kWh increments) and the communication data is 12. If the maximum value
is exceeded when Pr. 891 = "0 to 4", the value is clamped at the maximum value, indicating that a
digit shift is necessary. If the maximum value is exceeded when Pr. 891 = "9999", the value returns
to 0, and the counting starts again. In other monitors, the value is clamped at the displayed
