How to use

Connect the GB202 wattmeter between the mains outlet and the device to be measured, ensuring proper orientation and secure connections. Once powered, the LCD will show the instantaneous power reading in watts. For accurate readings, avoid measuring devices that exceed the device's maximum rated power. Read the display directly to monitor changes in consumption as devices switch on or change operating modes.

Recommendations

Place the wattmeter in a dry, ventilated area away from direct heat sources, and confirm the connected appliance does not continuously exceed the meter's upper range. Use the GB202 for spot checks, short-term monitoring and comparisons between devices to improve energy awareness and support decisions about appliance usage.
