system is higher than 125kPa. The pump operates for one minute, then
stops for one minute, then operates for one minute, and so on.
Example:
DOSING_PUMP AUTO Runs the carrier-air pump for one
minute, at one minute intervals,
whenever the pressure in the
1303’s doser system rises above
125kPa.
3.6.4 Starting Discontinuous Dosing
This interface job starts a flow of tracer-gas which is interrupted at
regular intervals during a given total dosing time – see
Fig.3.3 . The dis-
continuous dosing job comprises four data elements: the dosing valve
number; the total dosing time; the discontinuous dosing period-length;
and the dosing valve opening period, see section 4.2.3 .

Example:
DIS_DOSING 1,20,5,3 Starts a discontinuous dosing pro-
cedure through dosing valve num-
ber 1 for a total time of 20s. The
discontinuous dosing period-length
is 5s, during which the dosing valve
is open for 3s.
