Procedure

1) Follow sections VIII and IX to prepare sensors for

measurement.

2) Follow section VI to prepare standards / solution.

Standards should bracket and fall within the range of

interest.

One mL HI 4001-00 ISA is added to 100 mL of both

samples and standards Add stir bar and mix before

taking measurements.

3) Follow section VII; General Guidelines to optimize test

set-up.

4) During calibration it is best to start with lower concen-

tration samples first. Wait for a stable measurement

before recording values. Slightly longer equilibra-

tions are required at lower concentrations .

5) To prevent carry over and contamination of samples,

rinse sensors with deionized and dab dry between

samples.
