CHAPTER 7 THE MODE-MENU
SENSOR is OFF (menu point 7). For this determination the LIGHT-
SENSOR must be fixed instead of the sample in front of the
fiberoptics. When the routine is carried out, the LIGHT
AVERAGING function (menu point 6) is disabled. If it is afterwards
required, it must be manually enabled. After the LIGHT-
CALIBRATION the EXT.LIGHT-SENSOR (menu point 7) is in the
OFF-position.
When in ON-position, the DISPLAY is
continuously illuminated. It should be
noted, that this may cause considerable costs of battery power. When
in OFF-position, DISPLAY ILLUMINATION can be transiently
turned on for 40 s by pressing ON for 3 s.

instrument is switched off manually, the AUTO-OFF function is
enabled again (automatic reset to ON-position). The AUTO-OFF
function is also automatically enabled when battery voltage drops
