Description: Battery manualtest start and stop. It is an enumeration value. If the NMS notifies the SNMP agent that the node is set to 1, it means to start a standard manual test; If the NMS notifies the SNMP agent that the node is set to 2, it means to start a short manual test; If the NMS notifies the SNMP agent that the node is set to 3, it means to stop the battery test. Set the parameters, such as battery test time, and voltage when the battery test stops before the node controls the start of the battery test. If the parameters are not set this time, the system uses the configuration parameters by default; and if the battery test is started at the first time, the system uses the default value. Battery test can only start up in some conditions, so that the reason of Start of battery short test failed may be as follow: 1. Interval between this test and the latest AC outage or test is longer than the preset duration. 2. No major alarm is raised. 3. The number of healthy modules is greater than 0. 4. The number of battery strings is greater than 0.
