4.4 Temperature Calibration
The temperature sensor is factory calibrated. Calibrate the
temperature probe only if you suspect the temperature
errors that may have occurred over a long period of time or
if you have a replacement temperature probe. This
procedure offers offset adjustment of probe to ensure more
accurate temperature measurement.
In the event where there is no temperature sensor, this
procedure can also be performed for Manual Temperature
Compensation (MTC).
4.4.1 Temperature Calibration Without ATC Probe
1. Switch the meter on. Press the MODE key to select
temperature mode, [Temp].
2. Press the CAL/MEAS key to enter temperature
calibration mode. The primary display indicates the pH
value, and the secondary display shows the
temperature.
3. Press ! or " key to select temperature value that
matches the temperature reading shown in your
reference thermometer.
4. Once you have selected the correct temperature,
press CON key to confirm.
5. The CON indicator flashes for one second and
disappears.
6. Press CAL/MEAS key to return to the pH
measurement mode.
NOTE: To exit this program without confirming the
temperature calibration value, DO NOT press CON. Press
CAL/MEAS instead.
