MAINTENANCE OF THE KERATOMETER
The most common maintenance that must be
done is replacement of the bulb. The bulb is
located in the housing under the front of the
main body of the
instrument.
To remove the housing, turn the main body
of the instrument to the side and loosen
the two thumb screws that hold it in place.
Hold the housing and remove the bulb.
Replace the bulb, put the housing back and
secure it with the thumb screws.
