3.1.2 Hollow Cathode Lamp Turret
Eight lamps may be installed, two of which may be on at one time. For routine analysis in which the analysis
elements are known, it is convenient if all the lamps to be used in measurement (up to eight) are installed in the
turret and the lamp current values, lamp numbers (socket numbers) along with the other measurement
parameters are stored beforehand in the instrument memory. This then allows the required lamp to be
automatically set in the optical path by just loading the stored parameters.

CAUTION
1. When installing a lamp, after inserting the lamp in the hole in the turret, insert the socket having the
same number as the turret hole onto the lamp pins. Make sure that the socket is fully seated; if it is not,
there is a danger from exposed pins carrying high voltage loads. Also, when removing the socket, make
sure that this operation is performed only after the lamp current reads 0 mA or OFF.
2. Mount unused sockets on the turret pegs near the turret holes.
