temperature to ensure the calibration accuracy.
If the actual read out of thermometer is 39.6, modify the
temperature to 39.6 by pressing  or  . Then press “Start/Stop”
to confirm the input value.
d) Then the instruments will the automatically begin to heat to 100
℃
. Once 100C is
reched and held as constact, the decimal begins to flicker. After 20 minutes, the
user can read the actual value from thermometer.
Notes: Please read the actual value after 20 minutes’ constant temperature to ensure
the calibration accuracy.
If the actual readout is 101.5, modify the temperature display
to 101.5 by pressing
 or  . Then press “Start/Stop” to confirm
the input value.
Note: Pressing “Set” and “  ” simultaneously during the temperature calibration
indicates exiting the temperature calibration program. The adjustments will be
cancelled and the changed value will be of no effect.
3.2. Calibration with the External sensor:
a) Power on the machine and ensure that the temperature on the display is less than
35°C.
b) Put External sensor into a block well.
c) Press “Mode” key without releasing, press “Start/Stop” key
and hold for 3 seconds, it will enter into temperature
calibration interface, see the right. At this point, “ ”
displayed, which indicates entering into external temperature
calibration program. The temperature displayed is External
sensor’s current temperature and it begins to rise to 40.0°
automatically.
It will automatically display “ ” six seconds later.
