Calibration with Manual Entry of Buffer Values
Calibration with manual entry of buffer values is performed with one, two, or
three buffer solutions.
Protos displays the measured temperature.
You must then enter the temperature-corrected buffer values. To do so, refer to
the buffer table (e.g. on the bottle) and enter the buffer value belonging to the
displayed temperature.
Intermediate values must be interpolated.
All calibration data is converted using a reference temperature of 25 °C.
During calibration the module is in HOLD mode. Current outputs and relay
contacts of the module behave as configured (BASE module).
Caution!
Only ever use fresh, undiluted buffer solutions!
