the Clear General Offset option is checked, VISCPRO will clear the
(factory-preset) General Offset for all temperatures for the instrument.
This Instrument Setting cannot be restored except from a previously-
saved Configuration. It is not recommended that you exercise this option
without consulting with CANNON Instrument Company personnel.
To train tube sensors (required for miniAV-X operation at each desired
temperature setting) click the Service/Train Tube Sensors menu option
for the desired instrument. The Train Tube Sensors window will open.
Click the check box to select each desired option. Then click the Start
button to initiate tube sensor training.
Prewash option
Select this option if the tube needs to be cleaned and dried prior to
training. The Prewash option will execute a tube cleaning cycle prior to
beginning the sensor training.
Trip Point Only option
Select this option only if the tube sensor has been previously trained and
requires only a validation/adjustment of the trip point settings (the
electrical current level and fluctuations associated with the passing of the
sample meniscus). The Only option will reduce the time required to
accomplish these functions signficantly, but will not check/adjust basic
power levels for instrument operation.
NOTE
The miniAV-X will not test samples until sensor training has been per-
formed at the test temperature.
At the conclusion of the sensor training, the “Learned” indicators for the
top, middle and bottom sensors should display in green. If sensor training
has not been successfully accomplished, the “Opened” and “Shorted”
sensor indicators may provide helpful diagnostic information. Consult
