6.8 Diagnostics Menu
Pumps and Stirrer
Allows technician to selectively check the functionality of the pumps and stirrer.
Inputs Status
Allows technician to check the status of the external inputs. Once a function has been
assigned to a digital input, it disappears from the next menu of available functions for the
next input.
External Control
The analyzer can be directed to initiate an analysis or calibration cycle or change operating
mode under the command of an external controller using the digital input lines. A command
on the digital input is represented by a contact closure (as the programmed EVENT)
that occurs for more than 1 second. A new command received supersedes the previous
command; in essence it will interrupt the previous command to execute the new command.
• Analyze once
• RUN/STOP
• Calibrate
• Validate (the source is defined in the validation menu)
• Not assigned
Validate Grab Sample
This function is the same as ‘analyze once’ except that the result data does not get sent to
the analog output (4-20 mA), it is reported on the screen and the serial outputs.
Relays
Allows technician to selectively check the functionality of the four relays. The relay status is
shown next to the selected relay. Pressing the ENTER key toggles the state of the relay. The
relay initial status will be updated upon leaving this diagnostics menu.
Analog Output
Allows technician to selectively check the two analog outputs. Previous analog output
setting will be updated upon leaving this diagnostics menu.
LED and Detector Control
Allows the technician to check the functionality of the optics system and its individual
components. Also allows adjusting the detector preamp gain for the selected LED. Any new
setting of the gain or of the intensity of the LED will override any previous optics calibration
setting.
CONSULT before overriding any setting.
This diagnostics menu allows direct reading of the mV level detected at the preamp and it shows
the corresponding absorbance calculated. The internal electronics enclosure temperature and
the reaction cell temperature are also displayed for reference.

The default passwords are as follows:
Technician - 123***
