9.1 Routine maintenance
Periodically do the following:
l
Check the humidity indicator card in the EC100 enclosure. If the highest dot has turned
pink, replace or recharge the desiccant bags. Replacement desiccant may be purchased
from Campbell Scientific or obtained elsewhere. See the manual ENC10/12, ENC12/14,
ENC14/16, ENC16/18, available at www.campbellsci.com , for more details on recharging
desiccant bags.
l
Make sure the LED Status Lights on the EC100 panel are green. If not, verify that all
connections are secure and that the instruments are powered. Also check the individual
diagnostic bits for the specific fault. See
Table 10-2 (p. 48) and Table 10-3 (p. 48).
