Temperature Calibration

● Temperature Calibration
Temperature calibration is required to accurately match 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 conductivity electrode with DI (deionized) water and wipe it with tissue paper.
• Switch on the EC meter and plug in the conductivity electrode and temperature sensor.
• Dip the conductivity electrode in any buffer solution till 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.
