problem through alternative mounting attachments. When using an intake tube
longer than 50 cm, we recommend that you secure the tube to avoid excessive vibra-
tion and torque, as shown in
Figure 2-4 on page 2-12.
Operation in Cold Weather (<5 °C)
The instrument has a temperature setting that reduces the dissipation of heat in
cold weather. We recommend that you change the setting when the average ambi-
ent temperature drops below 5 °C. See
Advanced—Chopper Housing Temperature on
page 7-8 for details.
Extreme Humidity
In extremely humid conditions (that exceed the specifications of the instrument)
water vapor can be drawn into the LI-7550 and condense, which could result in
damage to the electronics. Under normal operating conditions, the heat dissipated
in the LI-7550 is sufficient to prevent condensation from forming on the elec-
tronics. However, if your site experiences condensing conditions on a daily basis,
the desiccant pack kit (part number 7550-950) can help prevent condensation from
forming inside the LI-7550. It includes a bottle (part number 6572-055) and desic-
cant (part number 9975-042).
To use the desiccant pack:
1
Cut open the silver Mylar bag and open the internal bag.
2 Pour the desiccant into the desiccant bottle and tighten the lid.
3 Write the installation date on the bottle label.
