4.1 Power the instrument on and off
1. Plug external power supply into an electrical outlet.
2. Turn the instrument on by pressing the power switch on the

wait about 20 seconds before turning the instrument on again, otherwise
the electronic and mechanical systems will be damaged.

2. Press OK to confirm the language selection. The self check will
start automatically.
Changing the language setting
The instrument functions in the selected language until the option is
changed.
1. While turning the instrument on, touch the screen at any point
until the list for selecting a language appears (about
30 seconds).
2. Select the required language.
3. Press OK to confirm. The test program subsequently starts
automatically.
4.3 Self-Check
Each time the instrument is powered up, a series of diagnostic tests
are performed automatically to ensure operation of major system
components.
This procedure, which takes approximately two minutes, checks the
system, lamp, filter adjustment, wavelength calibration and voltage.
Each test which functions correctly is confirmed with a check mark.
The Main Menu is displayed when power up diagnostics are
completed.
