Battery Measurements

Note
Ensure you are performing measurements while the recorder is set to RECORD. If the buoy
is setup to duty cycle and is in the rest/off state, you will be unable to take a measurement.
A voltmeter can be used to confirm the proper voltage is being supplied to the exterior
bulkhead connector on the bottom of the buoy where the cable is attached.
This should be done before a deployment and after replacing batteries to ensure the batteries
are in good condition.
1. Turn on Recorder Buoy running solely on interior batteries (not plugged into 36 V wall
adapter).
2. Place the negative voltmeter lead (black) into pin 1 of the MCBH8F bulkhead
connector on the battery pack end cap for the common connection (pinout below).
3. Place the positive voltmeter lead (red) into pin 7 (pinout below).
When new batteries are placed in buoy the voltage should be ~33 to 35.2 V
(full capacity of long-life alkaline batteries).
