Operation
Mode 1: Voltage Display
In this mode, the present voltage supply (V) and frequency (Hz) are
displayed. The line frequency is measured at a resolution of 1 Hz and
within the range of 40 Hz to 70 Hz.
Mode 2: Amps Display
In this mode, the present current strength (A) and the power factor (Cos
Φ ) received by the appliance are displayed. If the measured current
strength is less than 4 A, a resolution of 0.01 A is selected. Other than
this, it is 0.02 A. At a measured current strength under 0.02 A, only 0A is
displayed.
Mode 3: Wattage Display
In this mode, the power is displayed in W. To calculate the power
consumed by the appliance, the voltage, current and power factors are
multiplied. Pressing the 2-PRICE button in this mode calls up the
maximum wattage display. Pressing this button again displays the time at
which the maximum wattage occurred.
Mode 4: Operating Time
In this mode, the total time is displayed during which the connected
appliance has been switched on. The time is shown in hours and minutes
or, if the total exceeds 100 hours, in hours only. After 9999 hours, the
display flashes. To record the time, both the electricity meter and the
connected appliance must be switched on. If the appliance uses too little
current, the time is not registered. For information on resetting the
recorded total time, see “Resetting modes 4, 5, and 6”.
Mode 5: kWh Display
In this mode, the cumulative total electricity consumption by the con-
nected appliances (in kWh) is displayed. Resolution is 0.01 kWh; the
highest number displayed is 9999.99 kWh.
Pressing the 2-PRICE button displays how much electricity has been
consumed in total at the regular price. Pressing the button again displays
how much electricity in total has been consumed at the reduced price.
For information on resetting the recorded total electricity consumption, see
“Resetting Modes 4, 5, and 6”.
