14. CALIBRATION
The CAL function allows single point
calibration of the thermometer at 0°C (32°F)
to compensate for probe offset error. Use
the field calibration feature to improve
thermometer/probe accuracy.
The Temp-16 Precision RTD Thermometer
comes with a calibration lock function to
prevent accidental changes to calibration
settings. A field calibration can only be
performed when the function has been
unlocked. To unlock field calibration, follow
steps 1 through 4 in
FIELD CALIBRATION
UNLOCK
section.
To calibrate:
1. Pack sensing end of probe in a
container tightly packed with crushed ice
and filled with distilled water. Allow
temperature to stabilize.
2. Press and release the
cal
key for 3
seconds to enter the calibration mode.
The CAL indicator starts blinking.
Release the
cal
key.
3. If the measured temperature is from
-5°C to 5°C (23 to 41°F) when the
temperature reading is stable, press the
cal
key.
The CAL indicator will stop blinking, and the
reading will be set to 0°C (32°F). The CAL
indicator will remain in display, indicating
that field calibration is now active.
If “Err” is displayed, the displayed reading is
outside the above limits.
NOTE:
Press any key (except the
cal
key)
while in calibration mode to abort
calibration.
