Figure 9 Current Draw Test Setup
4)
Connect the ammeter and set it for the lowest possible scale.
5)
Read the current draw on the ammeter. Measured current must be £ 2 µA (micro-amps).
6)
Set the ammeter range to accommodate at least 5 A.
7)
Activate the ELT by placing the control switch in the “ON” position.
8)
Allow the ELT to transmit a 406 MHz burst, which occurs about 50 seconds after activation.
a)
Read the 406 burst current draw. The 406MHz burst will draw approximately 3A to 4A. Burst current
should not exceed 5A.
9)
Adjust the ammeter to a scale appropriate for reading less than 200 mA.
10)
Read the steady state current draw on the ammeter, which must be £ 95 mA.
11)
Disconnect the ammeter before the next 406 MHz burst.
12)
Deactivate the ELT by placing the control switch in the “ARM” position.
13)
Remove the test fixture and reinstall the battery pack in accordance with SUBTASK 25-62-30-450-001 on
