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 <

> <> keys while keeping the <RUN/EN-

TER> key depressed.
