3. If the microprocessor assembly feels warm and the display has a blue back-
ground, but is otherwise blank, adjust the Display Intensity control at the back of
the analzyer by turning it clockwise. If the display is still blank, call Cirris to
replace the microprocessor assembly.

is no blue background showing in the display, call Cirris to replace the
microprocessor assembly.
Problem
: Display shows a darkened row, or gibberish characters.
Possible Causes
:
• Display Intensity control is not adjusted properly.
• Scanner assembly is bad.
• Microprocessor assembly is bad.
Things to do
:
1. If both rows of the display are dark, try adjusting the Display Intensity control at
the back of the analyzer by turning it counterclockwise. If this does not solve the
problem, go to step 2.
2. Turn off the analyzer, disconnect the microprocessor from the rest of the system,
then turn on the microprocessor. The analyzer should prompt
10 V LO
. If it
does, the analog board or one of the scanner boards is bad. Call Cirris to replace
it.
3. If the problem is not solved after the microprocessor is disconnected, the micro-
processor assembly is probably bad. Call Cirris to replace it.
Problem
: When a cable is disconnected, the display still prompts
Please Verify
.
Possible Causes:
• A cable adapter is bad, or adapting cables are bad.
• The scanner assembly is defective.
Things to do
:
1. Remove the cable adapters from the analyzer while the analyzer is still on. If the
analyzer still prompts
Please Verify
, the scanner is probably defective. Call
Cirris to replace it.
2. If the analyzer prompts
Ready To Test
after step one is done, you have
unwanted connections in your cable adapters or adapting cables.
