3、 Working principle

YM2462Portable microwave power meter (RF power meter)It consists of three parts: a high-precision high-power device, a high-frequency probe, and a liquid crystal display. When the high-power microwave source is attenuated and then input into the thermocouple probe during testing, a high-frequency current flows through the coaxial transmission line to the load resistor, which acts as a thermoelectric conversion element. When absorbing microwave power, the load resistor produces a Peltier effect, causing the thermocouple node at the hot end toT₁Temperature rise, compared to the temperature at the cold pointT₂Generate temperature difference（T₁-T₂＝Δt) The Seebeck effect, which causes a thermoelectric force, and then the resulting thermoelectric force is directly appliedA/DConversion of analog and digital control circuits, drivingLCDThe required decoding will be directly read by the display to obtain the power reading.

4、 Instrument usage instructions

1When testing power, please operate the machine according to the diagram（2）Connect.

2The power measured above will be directly read on the monitor

3If testing an unknown power, please follow the diagram（2）Connect and then measure the power from small to large, with the maximum not exceeding the specified value10%.

4To prevent the attenuator from heating up and affecting the test accuracy during continuous high-power use, please refer to the diagram（3）Connection, please use length>100mmThe extension connector.

5If a continuous high-power test lasts for a long time,Attenuator temperature rise exceeds50⁰CIt is recommended to air cool the attenuator to ensure heat dissipation and testing accuracy.

6When the LCD display above the monitor shows“LOBAT”Or“LOMBATTERY”When prompted that the battery is about to run out, please open the back cover and replace it with a new one9VStacked battery.

7Due to the use of a special connector for the attenuatorL16orNAll types can be used.
