(a) Free Chlorine
Perform zero calibration (see "Operation").
Empty the vial and then add a DPD No. 1 tablet. Crush
the tablet with a clean stirring rod then add the water
sample to the 10 ml mark. Mix well with the stirring rod
to dissolve the tablet. Replace the cap tightly and place
the vial in the sample chamber making sure the
Δ
and
∇
marks are aligned.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/l free chlorine.
(b) Total Chlorine
Remove the vial and add one DPD No. 3 tablet to the
coloured test solution. Mix to dissolve with the stirring rod.
Replace the cap tightly and place the vial in the sample
chamber making sure the
Δ
and
∇
marks are aligned.
Wait for a colour reaction time of two minutes.
Press the ZERO/TEST key.
The method symbol flashes for approx. 3 seconds.
The result is shown in the display in mg/l total chlorine.
Rinse the vial and cap thoroughly after each test.

Repeating the analysis:
Press the ZERO/TEST key again.
New zero calibration:
Press the MODE key until the desired method symbol
appears in the display again.
Light absorption too great. Reasons: zero calibration not
carried out or, possibly, dirty optics.
Measuring range exceeded or excessive turbidity.
Result below the lowest limit of the measuring range.
