Product FAQ
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.
