Checking the Dewpoint (continued)
4 Turn on the dryer.
5 Turn on the portable instrument and ensure there is positive airflow through
the sensor.
6 Monitor the readout and allow ample time for it to stabilize before discon-
necting the portable instrument. Some dewpoint monitors require a substan-
tial amount of time for residual moisture to be purged from the sensor.
7 In the event the dewpoint is not satisfactory, refer to the Troubleshooting
section of the manual under Process Dewpoint alarm for DC2.
8 Stop the dryer and allow it to cool down. Then disconnect your portable
instrument and replace any pipe plugs that may have been removed.
9 Close side panels and start the dryer.
