4.3 Setting flow rates

Warning. The sample is dosed with sodium hydroxide and
the concentration, although low at first, increases if any
spillage is left to evaporate. Take care to dispose of the
outflow safely.
The flow rates of standard solution and sample through the
wet-section are preset at the factory. It is advisable to check the
flow rates prior to the initial calibration – see Table. 4.1, page 22.
The overflow from the sensor drains into a drain tundish that is
drained to waste via a drain tube.

4.3.1 Checking the standard solution 2 (high) flow rate

The flow rate is factory-set. To check the standard solution
flowrate:
1. Fill the standard solution container with standard solution
or high purity water.
At the transmitter:
2. Access the Calibration level menus by pressing the
key (below the icon).
