5. Temperature Calibration
The temperature readout must be calibrated or manually set before attempting pH
calibration.
5.1 Calibration Procedure
1. Switch the pH Cube to Temperature mode (see section 2).
2. Plug the temperature sensor (Part No 121245) into the Temp socket.
3. Place the sensor alongside a good quality mercury thermometer into a
beaker of room temperature water. Stir the sensor and the thermometer
gently to ensure an even temperature throughout the beaker.
4. When the reading has stabilised, adjust the Temp Cal. control until the
display shows the same temperature as the mercury thermometer.
5. The Temperature function of the pH Cube is now calibrated and is ready for
use.
5.2 Calibration Notes
1. Temperature does not need to be recalibrated unless the Temperature sensor
is replaced.
5.3 Manual Temperature Setting
Manual temperature setting is only available if the temperature sensor is not
plugged in.
1. Switch the pH Cube on and select Temperature mode (see section 2).
2. Measure the temperature of the sample solution.
3. Adjust the Manual Temp control until the display shows the measured
temperature of the sample solution.
