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
