NOTE: Remember to check the temperature calibration when replacing the ATC
probe. See section 4.4, "Temperature calibration" (page 12).
Appendix A: temperature curve selection (Ion 6 meter only)
Using the temperature calibration procedure described on page 12 of this manual,
you can achieve the ±0.5°C accuracy specified for this meter. However, to
optimize temperature performance, you may make an offset adjustment of the
temperature curve.
1.
Connect your temperature probe to the meter.
2.
Go to the pH calibration mode by pressing the
CAL key when the unit is in pH measurement
mode.
3.
Compare displayed value to a NIST certified
thermometer or other thermometer known to
be accurate. For best accuracy, place probe and
thermometer in a constant temperature bath, in
this example: 25°C.
4.
Press MODE key. Unit displays the default
curve temperature, in this example: 25.9°C
See figure
5.
Press the MODE key to scroll through the three
temperature curves. Find the temperature
reading closest to your actual temperature, in
this example: 24.8°C.
See figure
6.
Press ENTER key to confirm calibration.
The LCD flashes "CO", the meter then reverts
to temperature calibration mode for offset
adjustment.
See figures
8.
Use the
▲
and
▼
keys to fine tune the
temperature reading to your actual
temperature, in this example: 25°C.
6.
Press ENTER key to confirm calibration.
The LCD displays "CO", and the meter
then reverts to measurement mode.
