Normal meter operation continues while the new program is being downloaded and stored in 
FLASH memory. A new program generally does not affect the meter configuration and archive 
logs.

Once the program download is complete, the Mark III meter restarts in order to run the new 
program components. Daniel MeterLink issues a message that it must disconnect from the 
meter due to the meter re-start. Once the meter is re-started, re-connect to the meter with 
Daniel MeterLink.

6.8.1 Power disruption during firmware upgrade

If the program failed to download to a Daniel Mark III Ultrasonic Gas Flow Meter during a 
firmware upgrade, Daniel MeterLink can no longer connect to the meter or a message 

 is displayed when trying to connect.

It is possible for the meter to lose its programming if the meter power fails during a firmware 
upgrade process. If this occurs, follow the special procedure known as a Backup Upgrade 
described below, to make a connection to the meter and re-attempt the download process.

1.

In Daniel MeterLink, use the 

 menu and select

. 

2.

Click the 

 button to close Program Settings dialog.

3.

For Serial Port Connections: If you are connecting to the meter over a serial port, make 

sure you are connected to Port A or Port B on the meter Field Connection Board. Note: 
You can not program the meter from Port C if the meter is not currently running a 
program.
