What to do if my BIRD 4421A power meter has no power?
If the power meter isn't turning on, check if the AC power cord is correctly connected to a working AC outlet. If not, connect the power cord. Also, ensure the batteries are adequately charged; if they aren't, connect the AC power cord to an AC outlet to charge them.
Why is my BIRD Measuring Instruments power sensor not automatically detected by the 4421A?
The power sensor may not be automatically detected by the 4421A for the following reasons: The sensor cable may not be properly connected to both the power meter and the power sensor. In this case, connect the sensor cable. Alternatively, the sensor cable might be defective, and the solution here is to replace it.
What to do if the power sensor is not automatically detected by my BIRD Measuring Instruments 4421A?
If the power sensor isn't being automatically detected by your BIRD Measuring Instruments 4421A, make sure the sensor cable is correctly connected to both the power meter and the power sensor. Connect the sensor cable if it is not connected. If the connection is correct, the sensor cable might be defective and needs to be replaced.
Why battery remaining % does not agree with what is expected in BIRD Measuring Instruments?
If the battery percentage on your BIRD Measuring Instruments device isn't what you expect, the battery fuel gauge may have lost sync with the battery. To resolve this, connect the AC power cord while the device is running and wait for the battery indicator to display the plug icon. This indicates that the charge cycle is complete and the fuel gauge has resynchronized with the battery.
