5、Clearly see the power consumption of electrical appliances:
You are able to know exactly how much do your appliances (like rice cooker, induction
cooker, electric heater) cost in a day or a month, when using them to do the cooking or
boiling water. After that, you can see which one is the cheapest to use, comparing with
gas.
6、Clearly see how much you spend on your daily-used household appliances,
like Microwave Ovens and Washing machines:
Connect the ammeter with your appliances; reset the accumulated power
consumption to zero, and then turn on your appliances. When it finishes working, you can
exactly read how much the consumption is, and then switch to see Electric power charge,
you can see how much you need to pay for cooking or washing.
7、Does TV still consume electricity in Standby Mode?
Connect the TV with the ammeter, choose Power Measurement function, you can
clearly read its real power consumption when TV is in Standby Mode. This product can
measure electrical equipments with power as low as 1 watt. (If the power of electrical
equipment is 1 Watt, it has to keep on working 1 year to reach 1 KWH.)
8、How to set up air-conditioner in a good operation condition, to meet the
requirements of comfort and energy-saving?
When the ambient temperature, humidity and other things are changing, the
air-conditioner’s temperature or mode needs to be adjusted accordingly, to ensure the
comfortable and energy-efficient environment. You can choose the Power Measurement
function, or Kilowatt-Hour Measurement function or Operation Condition function, adjust
the air-conditioner’s temperature to select different operation modes (such as cooling,
dehumidification, ventilator and so on). This can help find out real power consumption of
air-conditioner in different operation modes. Finally, it helps you find the appropriate
operation modes under different weather conditions, which also meet your needs of
comfort and energy-saving.
9. Detect if the air conditioner or the refrigerator is under normal operation, if
it is necessary to add refrigerant:
Without special tools, it is very difficult for the laypeople to promptly find whether the
air conditioner and the refrigerator are under normal operation. This ammeter can help
you make it. Under normal operation, the operation power of air conditioner or
refrigerator should be close to the power rating shown on the label. Based on this, you
can use the Power Measurement function to detect the operation power, and then you can
tell if your air conditioner or refrigerator is under normal operation or not, as well as if
refrigerant is needed or not. If operation power is over greater (more than 20% greater)
or over lower (more than 20% lower), operation of your air conditioner or refrigerator is
abnormal. Over greater operation power indicates that the compressor or auxiliary fan
relayis over loaded. Blockage may exist in the ventilation system or pipeline, and it needs
cleaning; besides, there may be something wrong with the compressor or auxiliary fan
