4 MEASUREMENT
4.1
Automatic Temperature Compensation (ATC)
4.2
Manual Temperature Compensation (MTC)
Important: For MTC, you must disconnect the temperature probe.
1. Switch the meter on. Press the MODE key to select pH mode.
2. Press the CAL/MEAS key to enter pH calibration mode. The CAL
annunciator appears above the upper display.
3. While in pH calibration mode, press the MODE key to enter
temperature compensation mode. The upper display shows the
current temperature setting and the lower display shows the default
value 25.0 ºC (if the meter has never been manually set for
temperature) or the last manually set value if the meter has
previously set for MTC. If you have not set the current temperature
setting the upper display will also show the default value of 25.0 ºC.
4. Check the temperature of your sample using an accurate
thermometer.
5. Press ¿ or À key to offset the temperature to the measured value
from step 4.
6. Press ENTER key to confirm the selected temperature and return to
the pH measurement mode.
NOTE
To exit this program without confirming the MTC value, DO NOT press
ENTER key in step 6. Press CAL/MEAS key instead.
The meter will compensate pH reading for the manually set temperature.
For ATC measurements, simply attach the temperature probe into the
meter (see Section 2.2). The [ATC] annunciator lights up on the LCD.
NOTE
If you are using a temperature probe, the probe must be submersed in
the liquid you are measuring so that the sample temperature can be
recorded and compensated for.
