If the device is not listed, or the given value does not appear to work
correctly, the encoder calibration value can be determined using the
following procedure:

FOR TOWERS,

1. Set the encoder calibration value to 1000.
2. Insure that the tower is positioned to allow at least a meter

of travel in the upward direction at an easily measurable
height, and then set the current position reading to 000.0.
NOTE: It will be necessary to adjust the lower limit setting
to allow this.

3. Using

the

STEP keys, adjust the height of the carrier until it

is one meter above the start point.

4. Record the reading of the display, ignoring the decimal

point (i.e. 200.0 would be 2000). This is the encoder
calibration value. NOTE: If the value is below 1000, the
resolution of the encoder is low and thus the 2090 will not
provide 0.1 cm resolution, even though the display shows
that digit. If the value has gone past 9999, the encoder has
too many counts per meter and the 2090 can not correct for
it. In this case, contact ETS for assistance.

5. Enter this value for the encoder calibration value and reset

the limits and position information.

6. Test the tower by moving it a known distance and

comparing the display to the measured distance traveled. It
may be necessary to adjust the encoder calibration value up
or down slightly depending on the result.

FOR TURNTABLES,

1. Set the encoder calibration value to 3600.
2. Insure that the turntable is positioned to allow more than a

full revolution of travel in the clockwise direction and use
the STEP keys to run the turntable clockwise a few degrees
to remove any play in the table.

3. Mark the current location of the turntable against the ground
