2. Click Service/Temperature Calibration for the desired instrument.
3. To calibrate temperature, enter the current temperature reading to the
nearest 0.01°C into the Temperature: field, subject to the following:
A decimal point MAY be included as an entry.
The entered actual temperature must not cause a correction in tem-
perature greater than +/- 5.0 degrees.
4. Select the desired offset button.
When the calibrated target temperature is set, the appropriate offset is
applied to control the current temperature.
5. Click the Calibrate button to initiate the calibration of an offset
between the reference temperature and the current temperature.
Multiple corrections Multiple or successive entries of correction for any temperature are
permissible. A newly entered corrected temperature is mathematically
compensated with the previously entered correction and is stored in
memory by the onboard microprocessor as the latest correction.
Data entry errors The miniAV-LT will not accept temperature reference data outside the
parameters noted previously. If the amount of the correction (delta to
displayed temperature) is too large, the correction will not be accepted.
General/Current Offsets The General Bath Offset is factory-preset value affecting temperature
control at all temperatures and should not ordinarily be changed. The
Current Offset is the temperature adjustment applied to a particular
temperature to conform bath temperature control to your temperature
reference . Always click the radio button for the Apply As Current
Option when calibrating for a specific temperature.
Training sensors
It is necessary to train instrument sensors in preparation for sample
testing at a specific temperature. The training procedure establishes the
proper power levels for sensor detection of the sample meniscus. The
