6.2 Scanning 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:
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:
