CAUTIONS When Handling / Things to Know Before Use
Due to the different measurement point and measurement method, power measured using this product may differ from that
given by a power conditioner, power usage readings provided by a power company or measurements taken with another device.
About the Usage Environment
Measuring in the following situations may fall outside the range of the measurement specifications.
■ Where the current is very small
■ Where the current is skewed
■ Where the power factor is low
■ Where a strong magnetic field is present
Do not use the device in the following situations as this will reduce its lifespan and could cause operating errors.
■ Where the ambient temperature is outside the range - 10 to + 50 ℃
■ Where the humidity is above 85% RH or there is condensation
■ In direct sunlight
■ Where there is excessive corrosive gas, dust, salt or soot
■ Where there is excessive vibration or impact
■ Where there is rain or water droplets
The radio transmission range will be reduced in the following usage environments due to radio noise.
In such a case, the device may not function.
■ If glass wool encased in aluminium is used as insulation in a wall between the devices.
■ If the unit is attached to a metal wall.
■ If radio waves are blocked by the body of the person using the unit.
■ If a domestic appliance such as a microwave or computer or an OA device is within 2 m.
■ If a DC device such as a bell or motor is in use close to the unit.
■ If a mobile telephone or PHS phone is used close to the unit.
■ If a microwave base station is used close to the unit (less than 10 m).
■ If there is a strong electric field from a nearby television or radio transmitter or radio mast.
There are points where the radio wave becomes weak even within the wireless range.
In this product, the firmware may be updated via Home IoT Gateway to improve the functions.
When updating the firmware , about 1-2 MB of packet data is generated each time via the home internet.
(Packet data charges are paid by the customer)
Keep the body away from the unit over 20 cm, when using this unit.
This device is to be used with the N phase earthed. This device is not to be used with an IT earthing system.
Uses for this Product
This product is for use with the Home IoT Gateway (MKG100913) and cannot be used alone.
Power calculations are made based on currents measured using the Current Transformers (thereafter omit to CT) and
voltages from a voltmeter connected to the device.
This product includes a CT cable set for main line (MAIN) measurement.
Extending the CT and 2m Cable for Power Measuring Unit (MKG1510-DE, Optional item) enables voltage measurement of
Photovoltaics (PV) and storage batteries (SB).
