ments
You can perform pH measurements with or without a temperature sen-
sor as well as with the temperature sensor of an oxygen sensor or a
conductivity measuring cell. The measuring instrument recognizes
which sensors are connected and switches automatically to the correct
mode for the temperature measurement.
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 <
▲> <▼> keys while keeping the
TER> key depressed.
