Electronic control measurements
Roche recommends performing an electronic control measurement before the first
measurement of a shift or in accordance with local standards.
The electronic control measures a fixed resistor that is internally connected to the
parking positions of the 5 sensor cables. Actual values from both sensors in each of
the five channels are validated by comparison with a reference value defined by
Roche.
The electronic control criteria are configured in Configuration > Electronic QC.

Ensure that all sensor cables are plugged into the parking position and an analyzer
temperature of 37.0±1.0 °C has been reached before starting the electronic
control.

Choose Multiplate > Start electronic QC.
An instruction window is displayed.
If the temperature is outside the recommended range or if the software has been
running for less than 20 minutes, a message is displayed, advising you not to run
the electronic control measurement.
On these message windows, choose the No button to terminate the procedure or
choose the Yes button to continue the procedure irrespective. (This should only
be done in particular circumstances, e.g. if the software was shut down by
accident.)
