To train tube sensors (required for miniAV-LT 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 Points 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 Trip Points Only option will reduce the time
required to accomplish these functions significantly, but will not check/
adjust basic power levels for instrument operation.
NOTE The miniAV-LT will not test samples until sensor training has been
performed 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
with CANNON Instrument Company personnel if problems with sensor
training persist.
