Instruction Manual Mesotest II

7. Operating the Unit
7.1. Before Each Use
Please inspect the unit prior to each use to
make sure that:
- The unit is in flawless technical
condition.
- All cables and plugs are free of defects.
- You have connected the unit with the
mains cable which is intended for the
unit.
- You have inserted the mains plug into a
power outlet with a flawless protective
earth conductor.
7.2. Preparation of the Examinee
The eyes of the person to be
examined must be adapted to
darkness for ca. 5 minutes
before the examination.
This poses no problem if the Mesotest II
has been set up in a darkened room. If it
has been set up in a brightly lit room, the
examinee has to be adapted by having
him look into the unit for a
corresponding period of time.
If the person being tested wears spectacles
or contact lens, the examination is then
carried out with the spectacles or contact
lenses.
This should be noted on the test form sheet
(also the presence of tinted lenses, if any).
