II. Usage Scenario

Combining equipment parameters (voltage/current/thermal resistance/thermocouple/frequency analog output, 24V loop power supply, accuracy 0.05% FS), it is suitable for thermal engineering sites in power plants, chemical industries, metallurgy, heating, and water treatment.

1. On-site fault diagnosis scenario

In the event of faults such as data anomalies, display deviations, and equipment alarms in thermal systems in industrial production, the fault location can be quickly determined through this device.

2. Laboratory calibration and teaching training scenarios

In the metrology laboratory, it meets daily metrology calibration needs; through functions such as signal simulation, measurement, and parameter table lookup, it aids practical teaching. The equipment is easy to operate and the data is intuitive, making it suitable for zero-foundation practical training operations.

3. Outdoor portable operation scenario

The device is powered by a high-capacity rechargeable lithium battery, eliminating the need for an external AC power supply. With its lightweight and easy-to-carry design, it is free from the constraints of on-site power supply and is suitable for various mobile and outdoor operation and maintenance tasks.

III. Usage

ALKH512 operates through buttons and supports functions such as parameter setting, data query, signal measurement output, and more.

1. Signal measurement mode

Select the signal type (thermocouple, thermal resistance, DC current, DC voltage) using the plus and minus buttons; if a thermocouple/thermal resistance is selected, it needs to be matched with the corresponding scale mark (K, S, Pt100, Cu50, and other common models); after wiring is completed, the screen displays the measured signal value in real-time, allowing direct comparison with standard parameters to determine whether the device under test has errors or malfunctions. The data is refreshed in real-time, eliminating the need for manual data collection.

2. Signal output mode

Select the desired signal type and scale mark for output; set the output parameters (temperature value, current value, voltage value) using the plus and minus buttons, supporting fixed-point output and segmented gradient output; after setting the parameters, press ENT to confirm. The device will stably output standard signals, and the instruments and control systems connected to the backend can receive the signals in real time and perform verification as required.

3. 24VDC power supply mode

Connect two-wire and three-wire transmitters through the distribution terminal; the device stably outputs 24V DC working power, and can simultaneously activate the measurement mode to collect the output signal of the transmitter in real-time after power-on, achieving integrated operation of "power supply + measurement", simplifying the on-site wiring process, and improving calibration efficiency.

IV. Precautions

Wiring specifications: Strictly distinguish between input, output, and distribution terminals. High-voltage access and reversed positive and negative connections are prohibited to avoid equipment short circuits and burnouts. Wiring must be carried out under power-off or no-load conditions.

Equipment protection: Equipment needs to be calibrated regularly. Before operation, avoid strong electromagnetic interference and severe vibration. In high and low temperature environments, preheat and let it stand for 5 minutes before operation.

Battery maintenance: When the battery is low, stop operation and charge it immediately. Do not store the battery in a depleted state. When charging, try to avoid high-intensity operations to extend the battery's service life.

Parameter matching: When connecting thermocouples and thermal resistors, it is essential to strictly match the equipment scale mark. Choosing the wrong scale mark can lead to data deviation and verification failure.

Functional adaptation: To avoid overload and prolonged operation, the equipment can be stopped for cooling after continuous operation for several hours, ensuring stable operation.

V. Conclusion

The AILEIKE ALKH512 Thermal Engineering Treasure combines multiple functions into one device, offering portability, efficiency, precision, and stability. It integrates measurement, output, table lookup, and power supply capabilities, replacing traditional equipment such as signal generators, multimeters, and external power supplies. This significantly reduces the cost of carrying equipment for on-site operations. It is suitable for use in industrial sites, laboratories, metrology facilities, teaching and training scenarios, and more.
