13.1 Appendix 1: How to calculate the temperature coefficient
To determine the temperature coefficient of sample solution, use the following formula:
T
c
= ×100%
Where:
T
C
=Temperature coefficient
C
TA
=Conductivity at Temperature A
C
TB
=Conductivity at Temperature B
T
A
=Temperature A
T
B
=Temperature B
1. Press and hold the MODE key for 3 seconds to enter temperature setting mode.
2. Press
▲ or ▼ key to set the temperature at 25
o
C.
3. Dip the conductivity electrode and temperature probe into sample solution A.
4. Record the temperature value T
A
and conductivity value C
TA
.
5. Repeat the steps above, whilst dipping the electrode and probe into same sample solution B.
Make sure both sample solutions have about 5
o
C to 10
o
C difference.
6. Record the temperature value T
B
and conductivity value C
TB
.
7. Calculate the temperature coefficient of sample solution according to the formula shown
above.
8. Enter the calculated temperature coefficient into the meter.
