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.
