[0018] Examples, such as Figure 1-3As shown, a handheld operator for a centralized heat metering system includes a handheld operator body and an MBUS-to-485 module. The handheld operator body comprises a housing 1, keypad 2, a display unit 3, a battery compartment 4, and terminal blocks 5. Keypad 2 is located on the front of the housing 1 and is used to input operation signals to the operator body. Keypad 2 has 16 keys. The display unit 3 is located above keypad 2 and includes a display screen for displaying on-site debugging data. The battery compartment 4 is located on a side of the housing 1 and contains batteries that power the operator body. Terminal blocks 5 are located on the top surface of the housing 1 and are used to connect to a concentrator or MBUS-to-485 module. The housing 1 houses an MCU unit, a 485 demodulation circuit, and a communication module. The display unit 3, keypad 2, 485 demodulation circuit, and communication module are all electrically connected to the MCU unit. The batteries installed in the battery compartment 4 are electrically connected to the display unit 3, keypad 2, MCU unit, 485 demodulation circuit, and communication module.
