A.3 Setting the Gap

1. Move the toggle switch to the right; this will

turn on (enable) the Gap Setting Feature. The

Pilot (red) light will be illuminated.

Note: The motor should be OFF.

2. If the contact light (yellow) is illuminated, turn

the micrometer adjustment ring clockwise (as

you look down on the instrument) until the light

is no longer illuminated (see Figure A-5).

3. If the yellow contact light is not illuminated,

slowly turn the micrometer adjustment ring in

small increments (one or two scale divisions)

counter-clockwise.

Continue moving the micrometer adjustment ring

slowly counter-clockwise until the contact light

(yellow)rstturns on.THIS IS THE “HIT

POINT.”

4. Adjust the sliding reference marker, right or

left, to the closest full scale division mark (see

Figure A-6).

5. Turn the micrometer adjustment ring one scale

division to the left to meet the line on the sliding

reference marker. THE YELLOW CONTACT

LIGHT SHOULD GO OFF.

6. Youhaveestablishedthegapspaceneededfor

measurement. Now turn the toggle switch OFF

(left); the red pilot light should go off.

Theviscosityofelectricallyconductiveuids

may be affected if readings are taken with the

Electronic Gap Setting feature “on”. Be sure to

shut the feature “off” before taking readings!

7. Carefully remove the sample cup.

Note:

1. The cup may be removed and replaced without resetting the gap if the micrometer

adjustment ring has not been moved.

2. Remove the spindle from the viscometer when cleaning.

3. Re-establish the hit point every time the spindle is attached/detached.
