Period Scaler The totaliser equation works in seconds. If the totalised channel units are other than
‘per second’ a period scaler other than the default (1) must be entered. For example,
if the input channel is in litres per hour, then the period scaler would have to be the
number of seconds in an hour (3600).
Unit Scaler If, for example, the input channel is in litres per hour, the totalised value will be in litres,
unless the unit scaler is set to a value other than 1. If it is more convenient, the totalised
value can be in thousands of litres by setting the unit scaler to 1000. Setting the unit
scaler negative causes the totaliser to decrement rather than increment.
Scale Low/High The ‘zero’ and full scale values for the totaliser, as traced on the screen.
If A/B switching is enabled, a second set of scale low and scale high values can be en-
tered. ‘A’ values are used during normal operation. ‘B’ values are switched to by job
action, as described in
section 4.7 .
The remaining confi guration items are identical with the relevant items in Input Channel confi guration
(
section 4.3.3 ) except that Log/Linear scale type is not available. For job information, see section 4.7.
Note: Selecting ‘High’ compression in Archive confi guration may cause very high totaliser values
to be displayed incorrectly by the recorder and held incorrectly in the history fi le. This problem
may be solved by moving the relevant point to a group using ‘Normal’ compression, or by re-scal-
ing the totaliser to read (for example) TeraWatt hours instead of Megawatt hours.
