FAQ
What types of equipment can the BM500A test?
The BM500A is suitable for measuring insulation resistance on motors, power cables, switches, transformers, and household appliances. Its broad range makes it adaptable to both low‑voltage residential systems and higher‑voltage industrial equipment.
How does the LCD display improve usability?
The high‑contrast LCD screen shows numeric values and status icons clearly, allowing technicians to read measurements quickly without squinting. This visibility is especially helpful in bright environments or when wearing gloves.
Is the device safe for high‑voltage testing?
Yes. The tester’s ABS housing is non‑conductive, and the internal circuitry includes protective components that limit exposure to dangerous voltages. Users should still follow standard safety procedures, such as wearing insulated gloves and disconnecting power where appropriate.
Can the BM500A be calibrated in the field?
Absolutely. The tester includes a built‑in calibration routine that can be performed on‑site using a known reference resistor. This feature helps maintain accuracy without sending the device back to the factory.
What warranty and support does Hyuduo provide?
Hyuduo offers a one‑year limited warranty covering manufacturing defects, along with access to technical support via phone or email. Replacement parts and firmware updates are provided to ensure the tester remains reliable throughout its service life.
