2E AElectricity Consumption & Cumulative Time
Respectively switch to cumulative Electricity Consumption(EC) monitoring
interface (as shown in Figure 2) and cumulative Consumption Time(CT)
interface (as shown in Figure 3) by pressing “
▼” or “▲”, and the measuring
display ranges shall be 0.00-99,999kWh and 0-99,999 minutes respectively.
The measured electricity consumption value will be automatically stored, and
