Press the OVERLOAD key again, 4 digits appear of which the first digit blink.
Use the ↑UP or ↓DOWN key to set the value of the first digit.

Press the OVERLOAD key repeatedly to select the following digit. And further this
way.

After all digits have been set this way, press the OVERLOAD key again to conclude.
If no key has been pushed for approximately 1 minute absolutely, the process will be
ended automatically.
Note:
This energy meter do not protect against overpressure.
Energy Consumption And Costs
A. Window Of Totally Consumed Energy In KWh
The totally accumulated energy usage of the apparatus has been shown since the
beginning of measuring in KWh.
B. Window Of Total Usage Duration
a)
Here one sees the total time of energy usage of the connected apparatus. When
the costs continuously increase to exceed 999.999 $ that there is no more place
for decimal place, the costs will be shown in 9999.99 $.The total costs has been
based on the price which was introduced in the Price/KWh mode.
b)
The total time that the meter runs is shown in hours/minutes/seconds mode in
the bottom part of the LCD screen. The counting happens in seconds as long as
the 100 hours are not exceeded. It proceeds in minutes afterwards. Both the
energy meter and the connected apparatus must be in working order so that the
functioning time could be counted. If the apparatus consumes too little current
(<0.04A), any data and the duration being measured will not be indicated
(0.00A).
C. Price/KWh mode
The price per KWh is set and shown in this mode. The tariff which is set here
stipulates the "costs of consumed energy". Pass through the following steps to set the
price of energy.
1.
Press the PRICE key to blink the first digit.
Press the ↑UP or ↓DOWN key to set the first digit.
2.
3.
Press the PRICE key to let the second digit blink.
Press the ↑UP or ↓DOWN key to set the second digit.
4.
5.
Repeat step 3 and step 4 to set the third, fourth, fifth and sixth digit.
6.
Press the PRICE key again to conclude.
7.
The range of the price goes between 0.001 KWh and 9999.99KWh.
Press the ↓DOWN and PRICE key at the same time to erase the total costs and the total
usage duration for the KWh recording.
