Correction factor cS
The °C display shows the actual temperature at the unit's control sensor ±0.1°C.
This temperature does not correspond directly to the temperature in the circulator’s bath
and even less to the temperature of any external connected system. The temperature
difference is determined by measuring the actual current temperature using a suitable
measuring device (calibrated or gauged thermometer). The difference is a correction
factor ( C ) which can be entered and stored into the unit.
The resolution of the correction factor is 0.01°C, with a range of ±2.5°C.
To set the correction factor:
Press the menu key until cS is shown on the menu display.
Change the correction factor shown on the °C display using the value keys.
Press the enter key to store the new correction factor or the unit will continue
to use the old factor.
The correction factor may have to be changed if the temperature setpoint is changed.
After a short time the °C display automatically indicates the fluid temperature.
Example: Setpoint value programmed at the circulator = 70.7°C
Actual measured temperature in bath/system = 70.5°C
DeltaT = 0.2°C
Enter the correction factor = +0.20°C
The temperature displayed at the circulator will now match the external
system(70.5°C).
