User Manual for AML Oceanographic’s Micro

Using a Terminal Emulator
Establish serial communications with the instrument on your computer. Refer to the
"Communications" section of this manual for more information.
Once connection is established, ensure the instrument is stationary, and is not submerged
in water.
To turn ON Atmospheric pressure compensation, issue the
ZERO ON
command. This will
calculate and apply the offset required to compensate for current atmospheric pressure
conditions.
To turn OFF Atmospheric pressure compensation, issue the
ZERO OFF
command. This
will disable the offset.
Issuing the
ZERO
command again will calculate a new offset based on current conditions
Monitoring Real Time Data
Ensure the pre-deployment procedures have been completed (see page 4).
Ensure that the desired sampling settings have been selected and applied.
Plug the data/power cable into the instrument. If you power the instrument over a long
cable, please note the following:
o
Voltage drop due to cable resistance increases with cable length. The voltage drop
on a standard AML cable, with a standard Micro•X, is about 1 volt per 100m of
cable.
o
The instrument’s lowest voltage is 8 volts.
o
The instrument’s maximum voltage is 26 volts.
o
The voltage at the instrument, while sampling, must be above the shutdown level
for the instrument to operate.
If using a Pressure•Xchange™ sensor, use the
ZERO
command while the instrument is in
air (NOT submerged) to zero the barometric pressure offset.
Begin monitoring data using SeaCast or HyperTerminal.
Send the instrument down to the desired depth and return it to the surface.
Post-Deployment Procedures
When the instrument is pulled from the water it should be rinsed with fresh water.
Dry the area around the connectors with a clean cloth or compressed air prior to
disconnecting the plugs or cables.
Do not blow compressed air into the
Pressure•Xchange™ sensor. Doing so may damage the sensitive pressure transducer
diaphragm.
Remove the cable. Place dummy plug in the connector to protect it.
Dry the instrument and stow it securely.
