4.5.2 Lamp Replacement and Adjusting the Light Source Mirror

The lifetime of both the Deuterium(D

) lamp and the Halogen (WI) lamp is approx.

1000 hours. After prolonged use, luminous energy decrease in turn causing the level of
noise in the measured data to increase.

4.5.2.1

Lamp Replacement

WARNINGS

(1) The lamp is hot when lit. Therefore, before replacing the lamp, switch

off the light source and wait for at least 10 minutes.

(2) Before attempting to replace the lamp, turn off the power and remove

the power cable from the outlet.

CAUTIONS

(1) Loosen only the screws required for lamp replacement.

(2) When handling the lamp, ware clean, cloth gloves. Never handle the

lamp with bare hands.

(3) Never touch the mirror or any other optical elements by hand.

(4) If the lamp surface is contaminated, clean it with gauze soaked in

ethanol and wipe it with dry clean gauze.

Replacement of Halogen(WI) lamp

(1)

Slide the outer lid of the light source unit to remove it and then remove the inner lid

(Fig 4.8).

(2)

Pull out the Halogen lamp from the socket (Fig. 4.9 or Fig. 4.10).

(3)

Insert a new Halogen lamp into the socket.

(4)

For the DS type, adjust the light source mirror as described in Section 4.5.2.2.

For the iRM type, adjust the light source mirror as described in Section 4.5.2.3.
