CHAPTER 2 INSTALLATION 
Unpacking 
Power Supply Requirements 
The IMP+ operates from a DC supply of 11 –30V and will typically draw less 
than 0.06A. 
The compact one-piece construction of the IMP+ can be mounted easily 
using the integral nose thread (1.5" or 2" BSP/ NPT, dependent on model).  
When choosing a location to mount the Imp, bear in mind the following: 
•  For access to the LCD display and programming buttons it is 
recommended that you mount it in an area which is easily accessible. 
•  The ultrasonic signal path should be free of falling material and 
obstructions such as pipes, beams etc.  
•  The IMP 3 should be mounted at least 20cm (0.66 feet) above the 
maximum level of the material and be perpendicular to the surface. 
Whilst the IMP 6 and 10 should be mounted at least 30cm (0.98 feet) 
above the maximum level of the material and be perpendicular to the 
surface. 
•  The ambient temperature is between -20ºC and 65ºC.  
•  There should be no high voltage cables or electrical inverters close by. 
 
Important Notice 
All shipping cartons should be opened carefully.  When using a box cutter, 
do not plunge the blade deeply into the box, as it could potentially cut or 
scratch equipment components. Carefully remove equipment from each 
carton, checking it against the packing list before discarding any packing 
material.  If there is any shortage or obvious shipping damage to the 
equipment, report it immediately to Pulsar Measurement. 
Important Notice 
All electronic products are susceptible to electrostatic shock, so follow 
proper grounding procedures during installation.
