Preparation For The Tests - KERN ALJ-A02 Installationsanleitung

4 Preparation for the tests

- The balance must have been switched on for at least 8 hours and placed in a
suitable environment and at a constant temperature (see the
recommendations in the manual for the balance).
- Fill the container (scope of delivery 6) to 2/3 of its height with distilled water,
taking care not to overflow. See figure 13.
Please note
- The balance with the mounted evaporation trap is ready for testing after about
one hour. This time is needed to stabilise the humidity conditions in the trap
- The test tube (scope of delivery 6) gradually fills up while the tests are carried
out. We recommend starting each pipette test with sufficient free volume in the
test tube. The test tube can be emptied before the tests using either an
external pump or with another pipette.
- According to ISO 8655, the test liquid to be used in the pipette must be grade
3 distilled or deionised water (ISO 3696).
- The test liquid must be at room temperature
