Pressure Cartridge Tests
High-Voltage Stability
Te st
Tests high voltage accuracy and stability of all 16 high voltage
power supplies. Unused chip (DNA, RNA, or protein) required.
High-Voltage Accuracy
Te st
Check of the high voltage controller.
High-Voltage Accuracy
on Load Test
Check of channel-reference diode in transmission direction.
Autofocus Test Checks the focusing capability of the optical system. Autofocus
test chip required.
Laser Stability Test Measurement of stability of red laser signal.
Electrode/Diode Test Checks the photo diode and current-versus-voltage performance
of the bioanalyzer. Electrode/diode test chip required.
Pressure Offset Test The vacuum system of the pressure cartridge consists of a
pump and the corresponding tubes. This test calibrates the
pressure sensors to zero.
Pressure Control Test Checks that the bioanalyzer is able to hold the working pressure
of -140 mbar. During the test pumps stay on, while the system
tries to regulate pressure to be kept at -140 mbar. Cell Autofocus
test chip required.
