containing ice and water. Wait a few minutes for the probe to stabilize.
Press the CAL and LOG keys simultaneously and then switch the instru-
ment on. After a few seconds, the instrument enters the temperature
calibration mode. The CAL tag will come on. The primary LCD will
display the measured temperature or the - - - - message if the
measured temperature is out of range. The secondary LCD will display 0.0 °C
(First calibration point). The tag will blink until the reading has
stabilized.
Use the ARROW keys to set the reading on the secondary LCD to that of
ice and water measured by ChecktempC (for example, -0.1 °C).
When the reading is stable and close to the selected calibration point, the
CFM tag will blink.
Press the CFM key to confirm the calibration or the CAL key to leave the
calibration mode.
The secondary LCD will display 50.0 °C (Second calibration point).
Immerse the temperature probe and the ChecktempC into the second
vessel.
Allow a few minutes for the probe to stabilize.
The tag will blink until the reading has stabilized.
Use the ARROW keys to set the reading on the secondary LCD to that of
the hot water bath.
When the reading is stable and close to the selected calibration point, the
CFM tag will blink.
Press the CFM key to confirm the calibration or the CAL key to leave the
calibration mode.
Note: If the measured value is not close enough to the displayed value on
secondary LCD, the WRONG tag will blink. In this case, check if the
value set on secondary LCD and the temperature measured with
ChecktempC are close. Change the temperature probe and restart
calibration if necessary.
