6.1 Daily Care
Check the sample compartment
Check if there is spilled liquid on the floor of the sample compartment before and after use. Wipe off
any spilled liquid immediately to prevent evaporation and corrosion of the compartment, which may cause
erroneous result.
Clean the dust filter
There are four dust filters at the bottom of the instrument. Generally speaking, the user should clean
them every three months. But if in the places under severe conditions such as with much sand, it should be
cleaned once a month. Use tap water to clean the filter.
Refer to the appendix 2 for the clean method.
Surface cleaning
Do not spill solution on the cover. Otherwise, the cover will be blemished. If the solution spills on the
