Error Messages and Warnings
The instrument software is continually checking for errors. When an error is detected, an Error Message
dialog will be displayed. Select the "Dismiss" button to close the dialog. If a condition that could cause
damage is detected, any active tests will automatically be "Failed" and the sensor will be placed in the By-
Pass state.
For additional information on any error messages that may occur, their cause and possible solutions please
consult the Instrument Help System.
NOTE:
If you encounter an error message and are unable to resolve the problem, write down both
the error code and the message. This will help MOCON service representatives diagnose the
problem. Contact MOCON in the USA at (763) 493-6370.

Abrupt changes in display readings or long-term cyclic oscillations.
Unwanted data fluctuations observed during a test cycle may be caused by abrupt
changes in the carrier gas flow rate. Such a transient symptom can be produced by a
temporary restriction in a gas line, or gas usage by another system.
Regular, cyclic data fluctuations may also be observed in connection with ambient
package tests where the test packages are exposed to ambient temperature
fluctuations caused by frequent on/off heater and air conditioner cycles.
An Environmental Chamber (MOCON P/N 001-001) can be used when testing
packages to reduce or eliminate this problem.
When testing packages, this effect can also be minimized by placing a loose-fitting
plastic bag over the specimen, or by placing the specimen in an insulated box.
