HMP371 and HMP373 probes can be ordered as
temperature only probes. In the T-only probe version, humidity measurements cannot be
configured into use. The factory default output configuration for the T-only versions of
HMP371 and HMP373 is:
Channel 1: Temperature output
Channel 2: Output disabled
If you need to verify whether the probe in your transmitter is a T-only version, check the
configuration code on the product label. Figure 1. Location of configuration code on product label

If the 3rd digit of the configuration code is 4, 5, 6, or
7, the probe is a T-only version.
