•
Use nylon cord or other strong cable with any of the
holes on the mounting tabs. If wire is used to secure the
logger, make sure the wire loop is snug to the holes. Any
slack in the loop may cause excessive wear.
•
When deploying in water, the logger should be
appropriately weighted, secured, and protected
depending on water conditions and desired
measurement location.
•
If the TidbiT MX Temp 500 (MX2203) logger will be
exposed to sunlight in the deployment location, attach it
to a solar radiation shield (RS1 or M-RSA) using the solar
radiation shield bracket (MX2200-RS-BRACKET). Attach
the logger to the underside of the mounting plate as
shown. For more details on the solar radiation shield,
refer to the
Solar Radiation Shield Installation Guide
at
www.onsetcomp.com/manuals/rs1.
•
Be careful of solvents. Check a materials compatibility
chart against the wetted materials listed in the
Specifications table before deploying the logger in
locations where untested solvents are present. The
TidbiT MX Temp 500 (MX2203) logger has an EPDM O-
ring, which is sensitive to polar solvents (acetone, keton),
and oils.
•
The protective boot is designed with a magnetic button
that will interact with the reed switch located inside the
logger. This means you do not need to remove the boot
to start, stop, or wake up the logger (if On Button Push or
Bluetooth Always Off configuration settings have been
selected). If you remove the logger from the boot or if
the magnetic button in the boot is not working properly,
you must place a magnet on the logger where the reed
switch is located if you want to start or stop the logger
with a button push or wake the logger up. Leave the
magnet in place for 3 seconds to start or stop it or 1
second to wake it up.
Maintaining the Logger
•
To clean the logger, remove the logger from the boot.
Rinse both the logger and the boot it in warm water. Use
a mild dishwashing detergent if necessary. Do not use
harsh chemicals, solvents, or abrasives.
•
Periodically inspect the logger for biofouling if it is
deployed in water and clean as described above.
•
Periodically inspect the O-ring on the inside of the
battery cover in the TidbiT MX Temp 400 (MX2203)
logger for cracks or tears and replace it if any are
detected (MX2203-ORING). See
Battery Information
for
steps on replacing the O-ring.
•
Periodically inspect the boot for any cracks or tears and
replace it if necessary (BOOT-MX220x-XX).
Protecting the Logger
Note:
Static electricity may cause the logger to stop logging.
The logger has been tested to 8 KV, but avoid electrostatic
discharge by grounding yourself to protect the logger. For more
information, search for “static discharge” on
www.onsetcomp.com.
Battery Information
The logger requires one CR2477 3V lithium battery (HRB-2477),
which is user-replaceable for the TidbiT MX Temp 400
(MX2203) and non-replaceable for the TidbiT MX Temp 5000
(MX2204). Battery life is 3 years, typical at 25°C (77°F)
with a
logging interval of 1 minute and Bluetooth Always On selected
or 5 years, typical at 25°C (77°F)
when the logger is configured
with Bluetooth Always Off or Bluetooth Off Water Detect
selected. Expected battery life varies based on the ambient
temperature where the logger is deployed, the logging interval,
the frequency of connections, downloads, and paging, and the
use of burst mode or statistics logging. Deployments in
extremely cold or hot temperatures or a logging interval faster
than 1 minute can impact battery life. Estimates are not
guaranteed due to uncertainties in initial battery conditions and
operating environment.
To replace the battery in the TidbiT MX Temp 400 (MX2203)
logger:
1.
Remove the logger from the boot.
2.
While pushing down on the back of the logger, rotate the
cover counterclockwise. If your cover has lock icons, rotate
it so that the icon moves from the locked to unlocked
position. The unlocked icon will then line up with the
double-ridge on the side of the logger case (pointed out in
step 3).
3.
Use the small tab on the cover to lift it off the logger.
