• Moisture - Moisture can also affect the adhesive
durability.
• Permanence - Make sure the mounting location is
permanent for the duration of the recording period.
• Public access - If the logger location is too visible, people
may interfere with the readings. Make sure it is not too
accessible.
Using External Temperature Probes
Some Vaisala Veriteq loggers have external temperature
channel(s) for use with an external temperature probe. Using
the external temperature probe enables you to collect data
from hard-to-get-at locations, such as in duct work or under
pipe insulation.
You can use an external temperature probe with these
loggers, provided the probe was calibrated with the logger.
To use an external temperature probe:
1
Enable the desired channel on the logger (see “Enabling
and Disabling Logger Channels” on page 39). If you do
not need to monitor from the internal temperature sensor,
disable it to conserve memory.
Note: You can disable most unused channels - exter-
nal probe or not - to conserve logger memory.
One exception is the internal temperature chan-
nel on VL-1700 and SP-1700 Data Loggers.
