The unattended operation function is extremely useful when performing a long duration reliability test. The user has the ability to track the equipment operating status and also has the ability to view and report the status in real time through sms (short message service) based on the parameters set by the user. This relieves the technician of the need to be present at all times and reduces labor costs while still maintaining real time monitoring.
Collect and store the system historical alarm information and key historical data in accordance with the user requirements . This function also provides the ability to view the historical data in real time for analysis by the user
The user can select the optimal excitation level and power unit configuration related to the power needs of the actual test in order to save energy costs.
Authority to operate the test system can be set to different levels depending on the laboratory requirements. Implementation of authority levels helps to protect the specimen and the test equipment as well as maintain control and safety standards in the laboratory. Authorization levels can be set for different functions and operations of the test system.
Rea卜time communication with the power amplifier is achieved via an Ethernet connection. This connection allows the user to perform remote control operations from more than 1 kilometer away from the system. In addition the connection provides the user with an interface to retrieve relevant information from the power amplifier as well as acquire data and perform analysis of the power amplifier.
The user can set the system automatic shutdown process to begin upon completion of the test. In addition, the time management function provides the ability to view accumulated time data in real time which is convenient for scheduling and planning.
The maximum system force can be limited in real time by adjusting the system force limit parameters. Different limits can be set for each test profile. This feature can prevent large sudden force from the shaker due to external reasons that might damage the shaker or the specimen
Combined centralized control can be performed with other third party equipment such as a temperature chamber. This control capability provides the ability to assure the test parameters and safety requirements related to the environmental testing are consistent with test requirements. The centralized control can be achieved through a variety of flexible control modes (for example: hardware interlock control, 485 bus control or Ethernet) depending on the third party equipment requirements.
The self-test source function provides failure source information in the event a problem occurs during the test process and a failure stops the test. This function does not require additional equipment.
