YSI 9600 - Manual (Page 31)

that both the battery pack described in 3.3.1 above and the 9689 power supply can both be plugged in with
no concern about damage to the alkaline batteries.
CAUTION: Remember that it will ONLY be possible to power the 9600 with the 9689 for field
applications when a special 96XX cable with yellow plastic ends is used. While the 9689 can be used
with standard YSI cables for instrument set-up and data upload, it cannot be used to power the
instrument for actual field studies.
CAUTION: Note that, while physically compatible with the 9600 cables (see below), other YSI power
supplies such as the 6037, 6038, and 6123 should NOT be used with the 9600 since they do not supply
enough power to operate the pumps correctly, regardless of the cable used.
3.4 ATTACHING THE SECOND STANDARD BAG
For the Predeployment Check described in Section 4.2 below, the “sample” which is run should be
identical to the standard used for the deployment. To carry out this step, you must locate the second
standard bag which has tubing assembly attached to its middle port and which was filled with standard in
Section 2.4 above.
To install the second standard bag for the predeployment check, follow the step-by-step instructions below:
• Use the picture below to locate the inlet filter and its guard which are located on the top of the top plate
of the carousel.
Inlet filter and guard
• Remove the inlet filter guard by unscrewing it in a counterclockwise direction and set it aside for later
use.
• Remove the inlet filter assembly by unscrewing it in a counter clockwise direction and set it aside for
later use. Be sure to unscrew the entire assembly by grasping it close to the inlet port rather than
grasping just the filter itself.
• Lay the second standard bag on the top of the carousel and attach the white threaded fitting on its
tubing assembly to the inlet filter port as shown in the picture below. Tighten with finger pressure
only – no tools should be used.
