Troubleshooting the System
This section describes how to use the 800 system diagnostic tests to check the
functions of the system components. Access the tests from the Troubleshooting
menu or by pressing
Troubleshooting at the View Status screen. Table 4-2
describes the function of each test.
Fluidics Functions Tests the ability of the reagent components to deliver the
reagents to the fluid detectors in the reagent manifold and the
measurement module.
Pump Flow Rate Tests the ability of the reagent pump to pump a specified amount
of fluid in a specified period of time.
Pump Functions Tests the ability of all pumps to turn on and off and lets you
manually test the flow rates for these pumps.
Valves Tests the solenoid valve electronics and the ability of the valves
to open and close. The valves tested are 6.8, 7.3, foam, wash,
vent, clean, bypass, cal gas, slope gas, glu/lac, and diverter.
Gas Flow Rates Tests the ability of the Cal Gas and Slope Gas valves to control
the flow of gases.
Fluid Detector Tests the ability of the fluid detectors to detect the presence of
fluids and to detect whether the fluids are clear or opaque.
Sample Entry Tests the ability of the system to identify the position of the
sample door and of the sample probe and to detect the type of
sample device. This test can also calibrate the sample door.
Temperature/pAtm Displays the temperature readings for the measurement module,
the sample, the measurement module window, and the preheater.
The test also displays the atmospheric pressure.
Measurement Tests the measurement electronics by displaying sensor voltage
and current output.
COox Optics Tests the operation of the lamp on the CO-ox module and
provides the integration time of the last one-point calibration.
External Loopback
Tests the communication between the user-interface processor,
the serial ports, and the external cable connected to each port.
