Temperature Control

Oven temperature calibration

3.CALIB DELTA is displayed until ENTER is pressed; then oven temperature recalibration occurs. Note that, after calibration, the

displayed oven temperature value should match closely the measured value.

Any delta value within the range -10.00 through +10.00^C may be entered. If a value outside this range is entered, the message CORRECTION TOO HIGH is displayed.

Assuming the battery protecting HP 5890 memory is operational, a new calibration constant remains in effect even if the instrument is switched off, or disconnected from its power source, or if power fails.
