Main screen
Status bar
The status bar shows the current temperature of the measurement block. If the
temperature is out of range and a measurement is started, the operator is asked
whether to proceed against Roche’s recommendation.
In addition, the status bar informs the operator about possible analyzer errors or
service messages.
If the timer is started, the status bar displays the countdown of the timer.
Quick access buttons
The main functions of the analyzer are directly accessible on the main screen by the
use of quick access buttons. The same functions may also be invoked using the
function keys (F1–F9).
Channel display
Each channel consists of an information panel and a graphic window.
Three aggregation parameter values are displayed to quantify the measured signal:
o AUC: Area under the curve
q
The AUC is the recommended parameter for evaluation and interpretation of the
measurement.
The AUC result is the arithmetic mean of duplicate sensor measurements within one
test cell.
o Aggregation: Increase of impedance during analysis
o Velocity: Max. slope of aggregation
