双通道测量功能是PROVA903的一大亮点。它如同双通道示波器一般，可以同时测量电压+电压或电压+电流，还能同时显示频率（Hz）和波宽（%）。这种设计不仅提高了测量效率，还为用户提供了更全面的测量数据，方便进行复杂的电路分析和故障排查。

此外，PROVA903配备了RS-232C计算机接口，能够方便地与计算机连接，实现数据的快速传输和进一步分析。其记录器功能可记录10,708笔资料，配合免费软件，用户可以轻松地对测量数据进行存储、管理和分析，便于长期监测和研究。

PROVA903还具备电容量测功能，进一步拓展了其应用范围。在直流电压测量方面，其输入阻抗为10M，过载保护交流电1000V，确保了测量的安全性和可靠性。在交流电压测量上，准确度限定在20Hz~200KHz范围的5%-100%，能够满足多种应用场景下的交流电压测量需求。

The Taiwan TES PROVA903 High-Precision Dual-Channel Multimeter is a highly capable measuring instrument, boasting a best accuracy of 0.02% for DC and 0.1% for AC. It can provide extremely accurate measurement results. With a resolution of 60,000 and a precision of up to 4 5/6 digits, even the slightest changes in values can be precisely captured, meeting the needs for high-precision measurements.

This multimeter has a bandwidth of up to 200KHz, allowing it to handle measurement tasks across a wide range of frequencies. It supports true RMS measurement and features a fast ACV/ACA response. When measuring AC signals, it can more accurately reflect the true effective value of the signal and quickly respond to signal changes, thereby improving measurement efficiency.

The dual-channel measurement function is one of the highlights of the PROVA903. It works like a dual-channel oscilloscope, capable of simultaneously measuring voltage + voltage or voltage + current, and can also display frequency (Hz) and bandwidth (%) at the same time. This design not only enhances measurement efficiency but also provides users with more comprehensive measurement data, facilitating complex circuit analysis and troubleshooting.

In addition, the PROVA903 is equipped with an RS-232C computer interface, enabling convenient connection to a computer for fast data transfer and further analysis. Its recorder function can store up to 10,708 data points, and with the free software, users can easily store, manage, and analyze measurement data, making it convenient for long-term monitoring and research.

The PROVA903 also features a capacitance measurement function, further expanding its range of applications. In terms of DC voltage measurement, it has an input impedance of 10M and an AC overload protection of 1000V, ensuring the safety and reliability of measurements. For AC voltage measurement, the accuracy is limited to 5%-100% within the range of 20Hz to 200KHz, enabling it to meet the needs for AC voltage measurement in a variety of application scenarios.
