Standard Operating Procedures
In normal operation the only routine operation is to replace the memory card to retrieve the
data it has collected. At longer intervals, depending on the salinity of the water and the
weather conditions, the anchoring hardware should be replaced.
Replacing the Memory Card
Approach the buoy and hold it by the side of a small boat. Avoid letting the boat pull the
buoy’s anchor.
If the buoy is used in salt water, rinse the logger house with fresh water and wipe it until
dry with a lint-free cloth. When the hands and the instrument are salt free and dry, open the
spring. Hold the cylinder with both hands and push on the corners of the spring with your
thumbs. The locking spring is identical on the LogDators and on SediMeters.
Do not tilt the lid when opening or closing it
Follow these steps:
1. Turn on the display by clicking the NavPin in any
direction.1
2. Compare the next time on the first line with the
actual time on the second, and make sure no
measurement is about to happen during the time it
takes to replace the card (a few minutes).
3. Switch to Sleep mode.
4. Remove the memory card with the recorded data
(press it in to release it).
5. Insert a new memory card, with the label up, and
verify that the display reads “MMC Card Mounted”.

a. If nothing happens on the display after 5 s with an SD card, check that the
write protect slide is not engaged. If it is, unlock the card and re-insert.
b. If the display reads “MMC Card Error” followed by a two digit hexadecimal
number,2 the card is not mounted. Try again; sometimes it works after
several attempts since the card itself gets reset each time. If not, use another
card.
6. Verify that the real-time clock in menu 3 has not already passed the time of next
measurement in menu 5, and if it has, set a new Next time in menu 5
7. Switch back to Master mode (or Logger mode for stand-alone operation)
8. You can now verify in the display, menu 16, that the time of next measurement is
after the clock time (if not, switch back to Sleep mode and repeat from point 6)
9. Turn off the display
Closing
Make sure the o-ring and its groove and mating
surfaces are clean and that the o-ring is greased.
Place a bag of desiccant beside the display and put
the lid on.
Push the lid down until it makes resistance. At
that point give it a twist while pushing the last
distance. That way the o-ring more easily slides into
the cylinder.
Hold the lid down while you swing the locking
spring in place. Push on the bend of the spring to
make it mate with the groove on the lid. Some
springs, when they are new, may need a little bit of
help in opening up around the cylinder. Make sure it
slips into the groove all the way around. Also make
sure that the lower ends of the spring are not sliding out of their holes.
1
While a measurement is being taken the display will not turn on, so if nothing happens
wait a while and try again. If it cannot be turned on with repeated attempts during 3
minutes, remove the card anyway, then press Reset, and set up all measurements again (cf.
next section). If it does not start it either has no power, or has some electrical fault.
2
Error code 80 means that it cannot communicate at all, i.e., it is a non-supported card.
Code 08 means that it cannot read the partition table, which may be because the card is not
formatted in FAT16, in which case it must be formatted in a computer. However, code 08
may also appear if the card was not reset properly, so you may want to remove it, wait a
few seconds, and try again.

Preparing the Logger
We assume that all instruments are in place and the UW cables connected, with dielectric
grease on the contacts, and that the lid of the buoy is off.
1. For a complete restart, reset the LogDator. Verify that the display indicates the
memory status.
2. Insert the memory card. Verify that it gets mounted.
3. Turn on the display. Step through the menus (cf. below) from left to right.
4. Set Date, Time, Interval, Next At.
5. Verify that menu 6 says Store On Card.
6. Pass menu 7. If desired, clear the files on the card in menu 8.
7. Set burst sample count in menu 9, e.g. 84 (if there are no optional sensors, set 0).
8. Set burst sample rate in menu 10, e.g. 1.5 Hz (a good choice for the RH sensor).
9. In menu 11, either set to “NoChange”, or, to be sure that the slaves do not take more
time than the master, set to “Copy!f&#”.
10. In menu 12, select “RollCall” and click select. After less than a minute the display
will change to “n= xxx” where xxx should match the number of instruments on the
network (including the buoy). If not, identify and resolve the problem.
11. Return to menu 4 and verify that the Interval has not changed. If it has,
a. either select an Interval that is longer than the value in the display. Go to 12.
b. or select the original Interval, and go back to step 7 and change one or more
values in menus 9 through 11.
12. In menu 13, set Sleeping Pill On.
13. In menu 14, set Mode Master. It will now create the directory and files on the card.
14. In menu 15, verify that the system voltage is in the acceptable range (8.4 V to 9.2 V
means that everything probably is fine).
15. In menu 16, verify that the clock and time for next measurements are as set. Click
Select to turn off the menu.
Close the lid as described under Closing above.

Periodic Maintenance
Every visit
Check the floatation body for visible signs of damage, such as physical abuse or damage by
the sun. Inspect how deep it is in the water. If it looks damaged or starts sinking, replace it.
Every year
Check the anchoring. Lift the buoy up from the water and check the state of the shackle,
swivel, chain, rope, etc. If any link has deteriorated appreciably, replace that part. Also
inspect the clamps that hold the floatation body in place on the tube.
Every second year
Replace the floatation body. Disconnect the anchoring line and pull the old floatation body
off downwards. The bushings can be reused, but replace the clamps.
The standard buoy’s floatation ability is guaranteed for 2 years by its manufacturer,
Taylor. It may be replaced by any other suitably sized floatation body that fits over the tube
(the diameter of which is ca 51 mm). If metal is used, it should be of a similar material to
prevent galvanic corrosion. The tube is made of stainless steel type 316 (similar to A4 in
Germany and “syrafast” in Sweden).
Also replace the o-ring under the lid every second year.
Every sixth year
Replace the battery. It may need replacing sooner, if the voltage falls too much during the
night.
