4.6.1. Display Format

For each of normalising parameters the display will appear similar to that shown
below.

4.7. Diagnostic Mode

The detector levels, Analogue to Digital (A-D) levels, receiver gain, calibration
and opacity data may be examined from this mode. Press the

MODE

key until

number 4 appears in the top left corner of the display, and push the

ENTER

key

to enter the mode.

The

ARROW

keys will now select from the following, press the

ENTER

key to

select the displayed option.
