Command 

Notes 

Pn.nn 

Performs profile at a depth increment of n.nn, as set by the operator, in the 
current profiling units (see command #018).  e.g.: P0.25 takes a reading 
every 0.25 dBar, metres or feet as appropriate

Pressure Units 

#018;0 

Pressure is output in dBar 

#018;1 

Pressure is output in metres, calculated using simplified UNESCO formula 

#018;2 

Pressure is output in feet, calculated using simplified UNESCO formula 

Pressure Tare 

#009; 

Takes a single reading of the pressure sensor and uses the measured value 
as a Tare (note the ‘;’ in the command) 

#009;nn 

Sets the Pressure Tare to ‘nn’, a user specified value (entered in the chosen 
units as set with command #018) 
e.g: #009;10.3 sets Pressure Tare to 10.3 dBar metres or feet. 

#010 

Instrument responds with current Tare value
