Make sure that there are no fans blowing air onto the CubiScan 25. The scale is sensitive and
moving air can affect scale readings.
•
If there is no air interfering with the CubiScan 25, proceed to step 1 below.
Middle Dashes
Dashes in the middle of the weight field mean that the scale cannot find a stable reading. If you
have dashes appearing in the middle of the weight field, complete the following steps:
•
Middle dashes can sometimes mean that there is no communication with the scale. To verify
that the CubiScan 25 is communicating with the scale, go to
Menu > Diag > Scale
. If there is no
communication with the scale the
Wgt
field will display
No Com
. If there is no communication
with the load cells the
Wgt
field will display
NoLC
.

Make sure that there are no fans blowing air onto the CubiScan 25. The scale is sensitive and
moving air can affect scale readings.
•
If there is no air interfering with the CubiScan 25, proceed to step 1 below.
Top Dashes
Dashes in the top of the weight field mean that the scale is reading over the scale limit.
•
Make sure that there are no objects on the platform, especially objects that weigh over the
weight limit of 15 lbs.
•
If there are no objects on the CubiScan 25’s platform, proceed to step 1 below.
Complete the following steps if there are still dashes in the weight field.
1. Make sure that the glass platform and scale plate are securely in place.
2. Make sure that there are no objects on or leaning against the scale plate.
3. Make sure that the four thumb screws (two on each end of the scale plate) are not too tight.
They should merely hold the scale plate in place without restricting the scale plate’s
movement.
4. Make sure that all the controller box cables are securely attached.
5. Make sure that all load cell summing box cables are securely attached.
6. Make sure that there are no objects on the platform and zero the CubiScan 25 by tapping the
[Zero]
button that is found on the main screen. If an accurate weight is not displayed in the
weight field, continue on to the next step.
7. Calibrate the scale. For instructions on how to do this, see
“Scale Calibration” on page 13
