Allocation 
P1 and P2 
P*899 mA2  Allocation 
By default the mA output 1 will be representative of the reading obtained, as 
determined by the Mode P2-100.  
If  required,  mA  output  2  can  be  configured  to  be  representative  of  the 
average, difference or sum of two points of measurement.  
E.g.  Both  P1-100  and  P2-100  =  6    Volume  then  mA  Output  2  can  be 
configured  to  give  an  output  representative  of    volume  on  point  1  or 
volume on point 2 or the average volume of  the two points or the  sum of 
the volume for both points. 
The options available are as follows: 
mA 1 Output relates to Point 1. 
mA 1 Output relates to Point 2. 
mA 1 Output relates to average of Pt 1 & Pt2. 
mA 1 Output relates to differential of Pt 1 & Pt2. 
mA 1 Output relates to sum of Pt 1 & Pt2. 
Important Information 
When mA Output 1 is to be representative of the average or sum of two points 
of measurement, then both points must be set to the same units of 
measurement. In the case of flow P1-100 and P2-100 are set for 4 (OCM Head) 
or 5 (OCM Flow), then P1-706, P2-706 (Volume Units) & P1-707, P2-707 
(Time Units) must be the same.  And in the case of Volume then P1-100 and 
P2-100 are set for 6 (Volume) then P1- 605, P2-605 (Volume Units) must be 
the same.  
 
 
Important Information 
When both mA Output 1 and mA Output 2 are allocated to the same point of 
measurement, in order for them to output the same reading, both of the mA low 
value (P834/P892) and mA high value (P835/P893) must be the same for each 
mA Output.
