pH measurements
You can perform pH measurements with or without a temperature probe as
well as with the temperature probe 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 tempera-
ture 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 probe.
If a temperature probe is connected, it is indicated on the display by TP.
Note
When calibrating without a temperature probe (no TP display indicator dis-
played), enter the current temperature of the respective buffer solution man-
ually using the <
▲> <▼> keys while keeping the
depressed.
