liquid sample.

6.Depress the READ button and record the digital reading which appears in the display window.

If the reading differs from the value printed on the test glass by more than ±0.0001, repeat the measurement several times. Clean the measuring prism and test glass surfaces with alcohol, followed by water after each test.

If an error persists, make the following adjustment:

7.Turn the shadow line adjustment control slightly and depress the READ button. Repeat this procedure until the display agrees with the test glass value.

The shadowline will now be above or below the center of the crosshair reticle.

8.Insert the Allen wrench through the reticle access hole in the dis- persion correction wheel. Adjust the reticle until the shadow line passes through the center of the crosshair (Figure 2 & Figure 3a).

The instrument is now calibrated.

10.0 ILLUMINATOR BULB REPLACEMENT

DANGER: The glass envelope of the bulb may be extremely hot. Do not attempt to change the bulb before it is completely cooled or without wearing protection.

!WARNING: Unplug the refractometer power cord before attempting to replace the illuminator bulb.

The illuminator bulb can be replaced by removing the condenser sleeve (Figure 6). Always use the suggested replacement bulb (Catalog No. 13104620, pkg. of 3) for maximum efficiency and safety. After inserting a new bulb, the socket can be adjusted to center the light on the measuring prism with the condenser sleeve in place. If necessary, push down on the spring-loaded condenser sleeve lock pin and slide back and forth until the pin snaps into place.
