Warranty period

During the warranty period, we will repair or replace any parts damaged due to quality issue, without any additional charges. If the parts are damaged beyond the warranty period, only the cost of the accessories will be charged. In the event that the equipment is damaged due to human factors by the buyer, we will undertake repairs or replace the accessories at cost price. Furthermore, during the quality assurance period, we are obligated to provide technical services and support for all equipment failures attributed to non-human factors, excluding scenarios such as war, disasters, and human-induced force majeure events.

What are the functions and connection methods of the source meter guard side?

The role of guard is to do equipotential. When measuring small current (generally less than 1uA), when the path through which force hi passes has a relatively large differential pressure loop, guard can be used to do equipotential wrapping, so as to achieve low external leakage of force hi and ensure that the current measured by the source meter is the current obtained by the load. Generally, three coaxial lines are used for connection.
