4.3 Adjustment
4.3.2 Temperature Calibration
If there is a difference between the indicated temperature and
actual temperature (temperature measured by a calibrated
thermometer) in the check on temperature setting accuracy, the
difference can be corrected by temperature calibration setting.
For instance, if the actual temperature as measured by
calibrated thermometer is 39.5
°
C when the indicated
temperature of the column oven is 40.0
°
C, then set a value of
-0.5
°
C (offset value) for correcting the difference.
NOTE : 1. For temperature calibration, be sure to measure
temperature with a calibrated thermometer.
2. Difference from the actual temperature will vary
somewhat with the temperature setting. For the
temperature calibration, it is recommended to use the
most frequently employed temperature setting for
obtaining the difference. For temperature calibration
with two or more Chromaster 5310 column ovens,
make sure to correct all of the ovens at the same
temperature.
