6.7 Temperature Calibration
In this calibration procedure, the ATC probe is attached to the
meter and the ATC annunciator displays on the right hand
side of the LCD.
1. Dip the temperature probe into a solution of known temperature,
such as a temperature bath for a few minutes until the
temperature probe stabilizes. Determine the temperature of the
sample to be measured using an accurate thermometer.
2. To perform temperature calibration, press MODE key to select
the temperature mode.
3. Press SET TEMP to set the desired temperature to match that
measured value. The CAL annunciator lights up.
4. Select the temperature value using the numeric keys.
5. Press YES to confirm the selected temperature. The CON
annunciator flashes for one second and disappears. The meter
reverts to the pH measurement mode. The temperature is now
set to the temperature selected. Note: Temperature can only be
set between -9.9
o
C to 110.0
o
C.
IMPORTANT :
Always conform to the temperature limits of the
sensor probe (e.g. epoxy pH probes with a built in
temperature sensor should not be used or
calibrated at temperatures above 80
o C.) If
unsure, check with specifications of the probe.
