ProScale Model 150 
ProScale Model 150 is a general purpose measuring system with standard 
measuring ranges of 250mm (10”) or 450mm (18”).

ReadHeads, and any of several available Displays. This manual covers the 
operation of the General Purpose LCD Displays with Firmware (F/W) version 
2.1 or higher.  
Multiple  ReadHeads  connected  to  individual  Displays  or  data  acquisition 
units may be used on the same Scale simultaneously. 
Scale & ReadHead Installation 
ProScale Model  150 is  easy  to  install.  By following  the  basics  of  good 
installation,  reliable,  error-free  operation  can  be  expected.    ProScale  M150 
can be used in many different measurement applications, and with numerous 
types and brands of equipment. Therefore all installations will be a little 
different and it is the responsibility of the user to choose the bolts, screws, or 
other  mounting  hardware  that  guarantee  proper  installation  for  optimum 
operation. 
Note:  If a custom kit was ordered which contains instructions for installing 
this ProScale  on  a  specific product,  follow  those  instructions  rather 
than the installation and calibration instructions in this manual.
