SECTION 4
Used to totalise on the display in flow units larger than those entered at Pr.46 (max. flow
rate).
Enter 0 - Multiples by 1
1 - Multiples by 0.1
2 - Multiples by 0.01
3 - Multiples by 0.001
4 - Multiples by 0.0001
5 - Multiples by 0.00001
6 - Multiples by 0.000001
7 - Multiples by 0.0000001
e.g. If Pr.46 is entered as litres, at Pr.48 enter '3' to totalise the flow in
cubic metres.
Note:1. Up to 15 mins of totaliser data can be lost if the unit is powered down.
2. On returning to RUN mode after accessing PROG, the totaliser will speed up
initially to 'catch-up' with the totalised flow.
