P103 Input 2 (Optional) 
The 4-20 mA input is available as an option (Consult Pulsar for details of 
availability),  and  can  be  used  to  replace  the  transducer  for  applications 
where an ultrasonic transducer cannot be used.  
Use this parameter to set the second input device when  using in Average or 
Differential Mode, and P101 Transducer = 1 (Optional Auxiliary Input). 
Second Transducer input not required. 
Transducer is a dB3. Range 0.125 to 3.00 metres 
Transducer is a dB6. Range 0.3 to 6.00 metres 
Transducer is a dB10. Range 0.3 to 10.00 metres 
Transducer is a dB15. Range 0.5 to 15.00 metres 
Transducer is a dB25. Range 0.6 to 25.00 metres 
Transducer is a dB40. Range 1.2 to 40.00 metres 
Transducer is a dBS6. Range 0.2 to 6.00 metres 
Transducer is a dBMach3 Range 0.0 to 2.425 mtrs.

P105 Empty Level 
This parameter is to be set to the maximum distance from the face of the 
transducer  to  the  empty  point,  in  P104  Measurement  Units.  Note  this 
value affects span as well, (see important information below), so should be 
set before span. 
Important Information 
When using the dB Mach 3 the empty distance is measured from the end 
of the horn to the empty point in P104 Measurement Units.
