Section 4 Start Up
4.1 Power the instrument on and off
1. Plug in to the power supply (laboratory analysis) or insert the
battery (field analysis).
2. The push-button switch on the back of the instrument switches
the instrument on (press for about 1 second) and off (press for
about 3 to 5 seconds). An acoustic signal confirms that the
instrument has been switched off.
Note: Do not turn the instrument off and on in rapid succession. Always
wait about 20 seconds before turning the instrument on again, otherwise
the electronic and mechanical systems will be damaged.
4.2 Language selection
The LCM III software includes several language options. The first
time the instrument is turned on, the language selection screen will
appear.
1. Select the desired language.
2. Press OK to confirm. 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 self-check will start automatically.
4.3 Self-Check
Each time the instrument is powered, a series of diagnostic tests
are performed automatically to make sure 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.
Note: For further error messages during self-check, see Section 8 on page
55 .
