NOTE
After the UPEUa is replaced by the UPEUc, the UPEU power consumption data monitored by the M2000
will change. The power consumption data does not only depend on the output power but also on the data
collection method. The UPEUc and UPEUa use different methods for collecting power consumption data.
Therefore, the decrease in the power consumption shown in the M2000 after the UPEUa is replaced by the
UPEUc does not necessarily reflect the actual decrease of power consumption.
