Temperature measure-
ment in pH measure-
ments
You can perform pH measurements with or without a temperature sen-
sor as well as with the temperature sensor of a D. O. probe. The mea-
suring instrument recognizes which sensors are connected and
automatically switches to the correct mode for the temperature mea-
surement.
The following cases are distinguishable.
* If you do not wish that, you can:
– either disconnect the 2nd sensor and use the manual temperature
input or
– use an electrode with a temperature sensor.
If a temperature sensor is connected, it is indicated on the display by
TP.
Note
When calibrating without a temperature sensor (no TP display indicator
displayed), enter the current temperature of the respective buffer solu-
tion manually using the <

TER> key depressed.
