CHAPTER 3 HOW TO USE YOUR ULTRA 4
 
Operating the Controls 
There are two main operating modes for your Ultra 4, Run Mode and 
Program Mode. There is also a Test Mode, used for checking the set-up.  
Display 
The graphical display provides different levels of runtime information on the 
current mode of operation, and status of the remote communication.  Whilst 
in the Run Mode the ‘Main’ screen displays the current reading or 
measurement and its units of measure, along with status messages with 
regards to the Transducer, Echo reception and Fail-Safe Mode and relay 
activity. Additionally, it can be programmed to display up to 5 auxiliary 
variables and provide status messages on alarms, pumps etc. To scroll 
between run mode screens (Echo, Settings, Trend, Info and Big), use the 
left and right arrow keys. 
The ‘Echo’ screen shows the live echo trace of the point of measurement set 
up, with various viewing options available.  For further information of the 
options available please refer to the ‘Hot keys’ section later in this chapter. 
The ‘Settings’ screen shows details of the empty level, span and blanking 
distance for the measurement point set up.  And if relays have been 
programmed, a graphical representation of the ON and OFF setpoints of the 
relay(s) are shown. 
The ‘Trend’ screen shows live measurement information depending on what 
is selected within the ‘Trend Setup’ parameters P260-274.  Pressing the up 
and down arrow keys allows you to toggle between current and historical 
trending.  Pressing the up and down arrow keys will toggle between the 
different trend logs being monitored as set up in ‘Trend Setup’. 
The ‘Info’ screen is split into multiple pages.  These give information such as 
the current time and date, details of the unit, if there is a SD card inserted 
and what it is logging, amongst other information.  Pressing the up and 
down arrows allows you to move between the info pages.  
The ‘Big’ screen allows you to view the current measurement and 
measurement unit displayed on the Main screen in a larger, clearer font.
