14.2.3 Setting the RTA system correction value
RTA (Real Temperature Adjustment)
The display shows the actual temperature at the internal or
external control sensor with the selected resolution.
This temperature does not correspond directly to the tem-
perature in the circulator’s bath and even less to the temper-
ature in the external connected system.
The temperature difference is determined by measuring the
actual current temperature using a suitable measuring de-
vice (calibrated or gauged thermometer).
It is entered into the circulator as the correction factor RTA
and remains stored there.
A separate internal (i) and external (e) RTA value is assigned
to each of the 4 storable set temperatures.
The correction factor only refers to this one application. A
new correction value is required for any new temperature or
altered test setup.
