Product Q&A

Q:What are the main functions of the GDYZ-301A tester?
A:
It integrates three functions: resistive current test, current meter calibration of the monitor, and counter action test of the monitor.
Q:Can the device measure three phases simultaneously?
A:
Yes, it can measure the resistive current of all three channels (ABC phase) simultaneously with only one time connection.
Q:What is the wireless transmission distance?
A:
The wireless transmission distance is 1000 meters and above, provided the environment is empty and unobstructed.
Q:Does the device support wireless sampling?
A:
Yes, it supports wireless sampling, which is suitable for outdoor use or sites where the PT sampling wiring cabinet is far from the tested arrester.
Q:What is the battery working time?
A:
The main unit has a battery working time of 8 hours, and the voltage sampling box lasts for 12 hours.
