2.3.5 Performing Tests
When zero calibration is complete, remove the vial from the sample chamber and perform
the tests as described under "Method".
When the results have been displayed:
• with some methods you can change between different chemical species
• you can store and/or print out the results
• perform further analysis with the same zero
• select a new method
2.3.6 Ensuring reaction periods (countdown)
To ensure compliance with reaction periods there is incorporated a time delay, the
countdown.
• Press [TEST] key.
Prepare the water sample/blank as described in the
method description and place the vial in the sample
chamber. The display shows the countdown by
pressing the [TEST] key and the countdown is
started automatically. After the reaction period is
finished the reading starts automatically.
Notes:
1. It is possible to finish the working countdown by pressing the [ ] key. Reading starts immediately.
In this case the operator is responsible for ensuring the necessary reaction period by himself.
Non-compliance with reaction periods leads to incorrect test results.
