3.2 Temperature Calibration
For best DO accuracy, ensure that the
temperature is accurate. The temperature
sensor of the DO 6+ probe has been
factory calibrated, however if it changes
over time or if the probe is replaced,
calibration may be necessary. To protect
from erroneous calibrations, the allowable
tolerance is limited to ±5°C adjustment of
the factory default value.
Most users utilize automatic temperature
compensation using the sensor that is built
into the probe. However, manual
temperature compensation can be used to
input a fixed, known temperature.
1) Press MODE to select temperature
mode. The display should show “T”
for temperature and “A” for automatic
temperature compensation.
2) Dip the probe into a solution with a
known, accurate temperature (i.e. a
temperature bath). Allow enough time
for the temperature reading to
stabilize.
3) Press CAL. The CAL indicator will
blink above the display. The
temperature value shown is the value based on the factory default.
4) Press ▲ ▼ to adjust the reading to match the correct temperature value
(i.e. of the temperature bath).
5) Press HOLD/ENTER to confirm the calibration and return to measurement
mode.
Press CAL as needed to exit calibration without confirmation at any time.
