FAQ
Q1: Why is the measured value unstable?
A: The surface of the grounding terminal may have oxide film. Clean the contact surface or twist the test clamp to ensure good contact.
Q2: Can it work without AC power?
A: Yes. Built in lithium battery supports on site independent operation, convenient for outdoor and unmanned areas.
Q3: How to export test data?
A: Insert a U disk into the USB port, enter "Record Query" and select "Export Record" to complete data backup.
Q4: What is the benefit of 10A high current test?
A: High current can effectively break through oxide layer and poor contact points, making measurement more real and accurate.
Q5: How to maintain the battery?
A: Charge and discharge the battery at least once a month if not used for a long time; do not use the instrument when the battery is low.
