Multi 3400i Operation

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 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 <RUN/EN-

TER> key depressed.
