○ If the frequency reading is reasonable, but the corresponding pressure is not, this indi-
cates that the appropriate calibration is not loaded into the processor. Use the
LDDRUCK
program (see ADVField Software Manual) to load the
DRUCK
calibration.

3.9.5. External Sensor Commands – LISST-100 Sensor
These commands apply to systems that have an external LISST sensor installed (§4.12). The
LISST-100 is a Laser Interferometry and Transmissometry particle distribution measurement de-
vice designed by Sequoia Scientific.
LisstSensorInstalled Set [YES|NO]
• Selects or disables the LISST sensor (§4.12).
• Set at the factory. Does not need to be changed except in some special cases.
• The LISST sensor is a serial instrument that uses the second COM port on the ADVField’s
CPU board. As such, other serial devices (e.g., Paros, MicroCat CTD) must be disabled.
• When set to YES, LisstBufferSize is automatically set to 80 bytes (default).
LisstBufferSize or LBS [d]
• Default parameter:
80
bytes
• Without parameter: returns its current setting.
• When used with a valid parameter, sets the size of the LISST sample buffer.
