bar green (giving a value of between 10 and 30%) on the readout Á.
Once you are satisfied that the sample concentration is in the correct range you
can continue to the final stage of the measurement.
Caution
Do not spill any dispersant or sample onto the surfaces of the cover. It has been
found that certain substances can cause permanent damage to the covers. All
spillage should be scrupulously cleaned up immediately.
