Maintenance FAQs

 

Q: How to calibrate the instrument?

A: Annual professional calibration at authorized service centers is recommended. Users should not disassemble the device.

Q: What if test data fluctuates abnormally?

A: Ensure secure test lead connections and verify environmental temperature/humidity compliance.

Q: How to store the instrument when unused for long periods?

A: Store in a dry, ventilated area away from direct sunlight. Perform regular power - on maintenance.

Q: What to do if the LCD screen is blurry?

A: Adjust backlight brightness. If unresolved, contact after - sales service for screen replacement.

Q: Why can't the test current reach 100A?

A: Confirm stable power supply and avoid using excessively long or thin test leads to reduce line loss.

 

Summary: The 100A Loop Resistance Tester excels in precision, intelligence, and portability, making it an ideal tool for resistance testing in power systems and industrial applications. It empowers users to efficiently assess equipment safety and troubleshoot faults.
