Temperature Calibration
21
● Temperature Calibration
Temperature calibration is required to accurately match pH and conductivity electrode to the
meter. Check the temperature reading and if it is acceptable, no temperature calibration is
required. If you need to calibrate, please follow the procedure detailed below:
Prerequisites
• Clean the pH or conductivity electrode with DI (deionized) water and wipe it with tissue
paper.
• Switch on the meter and plug in the electrode and temperature sensor.
• Dip the electrode in any buffer solution until its temperature sensor is immersed.
• Wait for 5 minutes to ensure temperature stability.
• Meter displays
MTC
if the temperature sensor is not plugged in and displays
ATC
if the
temperature sensor is plugged in.
• Temperature calibration must be performed using a known temperature solution or against
a calibrated thermometer.
To abort an ongoing calibration process at any point of time, press the key.
