P815 Auxiliary Source 
When Ultra Wizard = 1 Level/Volume or 2 Pump/Differential  
When P100 = 4 (Average) or 5 (Differential) the auxiliary display line can 
be used to display the level on any of the two points of measurement.  
The options are as follows: 
 
P816 Totaliser (R) 
When Ultra Wizard = 2 Pump/Differential (Pumped Volume) or 3 Flow  
This  parameter  determines  whether  or  not  the  resettable  totaliser  will  be 
displayed in the auxiliary line of the display in run mode. When  selected, 
the  auxiliary  display  will  scroll  between  the  resettable  totaliser  and  the 
totaliser units selected. Default = 0 (Off). 
When being used to totalise Flow the resettable totaliser can be reset whilst 
in run mode via the “Totaliser” hot key   by pressing “0” whilst Total (R) 
is displayed. 
P817 Auxiliary Offset 
When Ultra Wizard = 1 Level/Volume or 2 Pump/Differential  
The value of this parameter is added to the reading of the auxiliary display 
before it is displayed, in Measurement Units (P104). 
Totaliser 
When Ultra Wizard = 2 Pump/Differential (Pumped Volume) or 3 Flow  
P820 Totaliser 
Displays the current value of the, non-resettable totaliser. During run mode, 
this  totaliser  can  be  viewed  via  the  “Totaliser”  hot  key,  .  Unlike  the 
resettable totaliser this totaliser cannot be reset whilst in run mode, it can 
however be reset whilst in program mode by accessing P820 Totaliser and 
entering zero.
