Does anyone happened to reset the forgotten password without RMA? We had tried the below but unsuccessful.
Using ION SETUP as below -> FAILED
Please find the way to change the password using Ion setup. Follow the steps mentioned. Open ION Setup then go to "diagnostic->trouble shooting ->change front panel password" Use ION Setup ver. 3.0.14290.03 or Higher Note that Default password: 0 In case if this process does not works then unfortunately there is no way to restore the password remotely. Meters needs to be sent for RMA to the factory. Note: In case meter will be sent to Factory for RMA , the process will also destroy all the data available in the meters.
For the 73xx devices, the front panel password is only for making changes via the front panel (over communications, there is no required password needed to be able to make any changes).
You will likely need to contact Technical Support to open a support ticket and provide device serial #s (which you have posted above) and proof of device ownership after which they will provide individual meter codes to allow you access to reset the front panel passwords assuming you haven't locked out front panel programming.
