The potentiometer should be calibrated once a month to ensure accurate
readings.
1. Place the potentiometer on the calibration stand. Place the stand on
the edge of the Consistometer and plug it into the port on the side of
the unit.
2. Connect the wire clamps to the contacts. From the groove going clock-
wise around the unit, connect yellow, then black, then blue.
3. Slide the weight into the groove and wrap the cord clockwise around
the unit one full turn.
4. Let the cord hang over the wheel and off the table.
5. Attach the hook to the cord.
6. Apply the weights to the hook according to the chart below. Steady the
cord to minimize the amount of swinging.
When adding weights, remember that the hook weighs 50 grams.
Therefore, to test the potentiometer at 200g, you only need to add 150g
to the hook.
7. Firmly tap the surface of the calibration stand with a pen or the blunt end
of a screwdriver to settle the weights and stabilize the potentiometer.
