Automatic Buffer Recognition (Calimatic)
Automatic calibration using Knick Calimatic is performed with one, two, or
three buffer solutions. Protos automatically detects the nominal buffer value on
the basis of the electrode potential and the measured temperature.
Any sequence of buffer solutions is possible, but they must belong to the buffer
set defined during parameter setting.
The Calimatic takes the temperature dependence of the buffer value into
account. 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 which belong to the selected
buffer set!
