b. Scale Illumination. Scale illumination can be increased by adjusting bulb contact to provide maximum bulb

brightness. If additional illumination is desired, remove the hood and loosen the knurled head screw (7, fig. 2-30) which

holds the cover on the recessed lamp housing in the left rear of the balance. Slide the cover from side to side and up

and down until the desired illumination is obtained. Tighten the knurled head screw firmly while holding the cover in

position. A replacement bulb is available and is stored in the lower spare mount.
