Option Description
Unit
Select the temperature unit that shows on the display—Celsius (default) or
Fahrenheit.
trEF
Enter the conductivity reference temperature for temperature correction—15.0 to
30.0 °C (default = 25.0 °C).
tC
Enter the conductivity temperature compensation factor (linear)—0.00% to 9.99%
per °C (default = 2.00% per °C).
The correction factor may need to be identified experimentally. For example, the
factor for ultrapure water is 4.55% per °C and the factor for NaCl salt solution
2.125% per °C.
AOFF
Set the auto-off feature to on (default) or off. When set to on, power is automatically
set to off after 8 minutes of no activity.
