6. MEASURING METHODS
The meter is a multiple measurement function of AC
power meter.
Those functions are voltage, current, watt, va, frequency,
power factor, power consumption and actual cost of
power consumed measurement.
Installation:
1. Turn off the appliance and remove the power cord
from the outlet. Connect the meter to the outlet and
appliance to the meter.
2. LCD display will show measuring value.
6-1. Main buttons functions of power meter
MODE Button :
You can select different modes by pressing MODE
button.
These modes are watts, power factor, apparent power,
frequency, AC voltage, AC current, kWh, GAS, cost and
time mode.
SELECT Button :
When the main modes are watts, apparent power, AC
voltage, AC current modes, press the SELECT button
can see the detail of maximum and minimum on the
display.
Other main mode like kWh, GAS, COST mode when
pressing the SELECT button, you can see the detail of
REAL, HOUR, MTH duration on the display.
Under the time mode, press the SELECT button can
select different display of time mode, (min/sec) mode,
(hours)mode, (days/hours)mode.
