Disassembly
1.
Remove the four screws holding the evaporation gauge cover and lift the cover off.
2.
Remove the chain from the sprocket by lifting the counterweight. Drape the counterweight and
chain over the outside of the gauge. Do not attempt to remove the float.
3.
Rotate the sprocket by hand to verify that it turns freely 360° without binding. It should spin freely
when given a small push.

Setup
1.
Note that one ridge on the sprocket face has been painted with a white stripe. The other ridges are
not painted and are spaced 60° around the face of the sprocket. The back side of the sprocket has
similar ridges but none are painted.
2.
Connect the reader to the evaporation gauge and verify that it responds to small movements of the
sprocket. Remember, the display updates only once every 15 seconds. Be patient.
Procedure
1.
Adjust the position of the sprocket until the display reads 9.00"
or 228.6 mm. The white stripe on the
front
of the sprocket
should be at approximately 1 o'clock position as viewed from the
front.
2.
While looking at the
back
of the sprocket, use a sticky-note as a
pointer and apply it to the top of the evaporation gauge housing,
aligning one corner to point at a rib on the back side of the
sprocket.
3.
Enter the measured value as the starting point in the table (next
page).

4.
Rotate the sprocket 60° counter-clockwise to the next ridge and record the measured value.
5.
Continue recording measurements in 60° increments.
