Working with individual probes or with a group of probes

Working with individual probes

Probes just discovered by HW4 (HW4 Main Menu Bar > Devices and Groups > Search for Master Devices >
USB Masters) are shown individually in the Device Tree.

At any time only one probe can be selected in the Device Tree. After selecting a probe, the user can start
measuring water activity with that probe.

HW4 can run several water activity measurements concurrently. Select any probe and start measuring water
activity with that probe. Select another probe and start measuring water activity with that other probe. The
water activity measurement process (AwQuick or AwE mode) runs independently for each probe. When
measuring water activity with several individual probes simultaneously, it is incumbent to the user to change
from time to time the probe selected in the Device Tree so as to find out when the measurement is ended.

Note: the bottom of the form has 3 text fields labeled “Batch Number”, “Product Name” and “Comments”. The
contents of these fields will appear on the water activity measurement report, assuming that the user decides
to generate such a report. To customize the contents of these fields for each probe, wait until one of the
probes is done and enter a text in each field just before clicking on the “Generate report” button. Select
another probe and proceed in the same manner.

Working with a group of probes

Probes that have been discovered by HW4 can be put into a group created by the user as illustrated below:

Working with a group of probes offers the convenience of monitoring all probes at the same time. However,
the contents text fields labeled “Batch Number”, “Product Name” and “Comments” are shared by all probes
within the group and cannot be customized for each individual probe.
