13.2.1
Tungsten Halogen Lamp Replacement
This option is only valid for the 7410 Spectrophotometers. We recommend the equipment is turned onto its side
to allow easy access to the lamp holder cover located on the underneath of the equipment (refer to section 2.3).
Wear ‘lint free’ protective gloves when replacing the lamp to prevent marking the lamp with finger prints.
I.
Remove the screws and lamp holder cover.
II.
Disconnect the electrical connector.
III.
Remove the two fixing screws and washers which retain the lamp assembly.
IV.
Grab the two tabs on the plastic lamp assembly and remove the whole lamp assembly, this may need to be
rotated slightly to allow it to be removed.
V.
Carefully remove the replacement lamp from the packaging. Ensure that the glass portion of the lamp is not
touched as finger marks will damage the lamp resulting in a reduced performance. If accidental damage
occurs the surface of the lamp may be cleaned using propan-2-ol.
VI.
Insert the new lamp assembly into the same position as the one just removed. This may need to be rotated
slightly to be fully inserted. Ensure that the fixing studs on the plastic lamp assembly line up with the fixing
holes in the unit.
VII.
Replace the two screws and washers removed earlier back in position to fully secure the lamp assembly. It
must be fully pulled against the black aluminium fixing plate.
VIII.
Reconnect the electrical connector.
IX.
Replace the screws and lamp holder cover ensuring no wires are trapped.
