6.2Scanning For Sondes You must be in Extended Programming to use a sonde with the 6712. The sampler can automatically scan for the presence of sondes if you enable that option:

•From the main menu, select OTHER FUNCTIONS.

•Select HARDWARE.

•As you press ↵ to move through the hardware screens, you will see one that looks like the following:

↑NO SDI-12 SONDE

AUTO SDI-12 SCAN OFF

↓

Select “NO SDI-12 SONDE” to scan for sondes. If one is found, you can set it up, and the “AUTO SDI-12 SCAN” option will be switched to yes.

Select the “AUTO SDI-12 SCAN” option to manually turn on (or off) automatic scanning for sondes when the sampler is turned on.

If a sonde has already been connected and set up, the hardware screen will instead display a screen similar to the following:
