them.
4.5.1 Main dialog with two measuring channels
The view with two measuring channels is displayed after the instrument
start-up.
NOTE
This does not apply for the 912 Conductometer, as this instrument
has only one measuring channel.
NOTE
Temperature display
The temperature displays on the two measuring channels can only be
compared in the same medium.
As a result of temperature sensor and instrument tolerances, the dis-
played values might deviate from each other.
