You are asked for the password regardless of the password protection
setting in your meter. Type the meter password, and click OK. If you
did not change the password in the meter, enter the default password
0.
Wait until PAS completes upgrading your device. It takes about 3-4
minutes at 115,200 bps to download the file to the meter.
After upgrading firmware is completed, the meter restarts, so
communications can be temporarily lost. You may need to wait a short
duration until PAS restores a connection with your device.
