Fault Indicator 4 Test Procedure: Procedure 1: Storage/Air Transport, Procedure 2: Operation/External Flight, Procedure 3: Rapid Decompression and Procedure, Procedure 4: Explosion Decompression, confirm the test procedure or combination of test procedures according to relevant document requirements. Temperature and humidity controller battery low battery alarm indication: When the battery voltage in the indicator drops from 3.6V to 2.7V, an alarm signal is generated to prompt maintenance personnel to replace the battery. Fault indicators refer to devices used to detect short circuits and ground faults. When detecting circuit faults, use it in conjunction with a fault locator. At present, in China, a large number of fault indicators are used when troubleshooting line faults. Remote transmission of alarm information on live display: The indicator host can drive corresponding relay actions based on different alarm indication signals for remote transmission of signals When selecting the test program, representative factors that the equipment is expected to be exposed to the worst low voltage conditions should be considered. When selecting the test program, the following should also be considered:
a. The technical status of the equipment B. Equipment work requirements C. The purpose of the equipment The data required to determine whether the equipment meets the job requirements E. Sequence of test procedures
