4.5.2.3 Adjustment of iRM type light source mirror
When the light source is replaced, if the beam from the lamp is not correctly incident
upon the entrance slit, troubles will arise, such as lack of luminous energy, bend of the
baseline, and deviation of the measurement value. Whenever the lamp is replaced, be
sure to adjust the light source mirror.
WARNINGS :
(1) The lamp is hot when lit. Do not touch with bare hands.
(2) Wear glasses (ordinary glasses or sunglasses) during adjustment to
protect your eyes from ultraviolet rays.
(3) Do not touch the wiring either with your hand or with a screwdriver.
Contact with the wiring may cause electric shock.
CAUTION: Loosen only the screws required for adjustment.
