PULSAR MEASUREMENT

When in Program mode the display is used to read information using a 
sophisticated progressive menu system, where parameter numbers can be 
entered, their details viewed, and values changed to suit the application. 
During Test Mode, the display is used to monitor the simulated level. A bar 
graph is also provided which will provide a visual reading of the level, in 
percentage of span. 
Run Mode 
This mode is used once the Ultra 4 has been set up in program mode. It is 
also the default mode that the unit reverts to when it resumes operation 
after a power failure.  When the Ultra 4 is switched on for the first time, it will 
display, in metres, the distance from the transducer face to the target. All 
relays by default are switched off. 
After programming is complete, any relays that are set will operate when the 
level reaches the relevant setpoint, and the small square box will become 
solid.  The letter in the box indicates the relay type.
