1. Basic Parameter Category

Q1: What are the voltage and current test ranges supported by the equipment? Is customization also available?
A: The voltage range of the standard model covers 0 - 600V. The current range is adjustable (for small current, it is 0 - 10A; for large current, it is 0 - 100A and above with an external transformer option). For large power industrial equipment and high-voltage testing scenarios, custom range support and expansion of range through external transformers are available, enabling compatibility with products of different power levels for testing.

Q2: What is the testing accuracy level? Is it suitable for high-precision detection scenarios?
A: The product is equipped with a high-precision testing accuracy of 0.5 grade/0.2 grade. The frequency response and industrial frequency testing errors are extremely small, with strong stability. It fully meets the ISO quality inspection standards, laboratory research and calibration, export product safety compliance testing, and mass production precision inspection scenarios that require high precision.

2. Adaptation Usage Class

Q3: Which devices or industries can it be compatible with?
A: It can conduct power consumption, efficiency and performance tests for a wide range of products such as household appliances, lighting fixtures, power adapters, frequency converters, motors, charging piles, photovoltaic components, and new energy small appliances. It is applicable to scenarios such as quality inspection on electronic factory production lines, third-party testing laboratories, university research, equipment factory calibration, and compliance testing of export products.

Q4: Does it support multiple voltage and frequency standards? Is it compatible with industrial environments in overseas regions?
A: The equipment supports global standard power grid, and can be compatible with power grid frequencies of 50Hz (used in China, Europe, and most countries in Asia), and 60Hz (used in the United States, Southeast Asia, and many countries in the Americas). It is compatible with industrial power usage environments across all countries in the world, with no regional usage restrictions.

Q5: Is data export and remote control supported?
A: The high-end model is equipped with RS232, RS485 and USB communication interfaces. It can be connected to a computer to collect test data in real time, generate test reports, and export Excel data. It also supports remote control from the computer end, data storage, and historical data query, and is suitable for unattended testing on automated production lines.
