3-12 Operating the Detector
Tip:
The detector does not have a polarity setting because the detector signal
measures and outputs either concentration/mass or temperature, which are
always positive numeric values.
0 – See 0-9 above. Cancel – Backs out of a
prompt without completing
the task. The word “Cancel”
appears as a cue in the lower,
right-hand border of the
message.
• – Enters a decimal point.
Also positions the cursor at
the last entry in a list.
+/– – Enters a
positive/negative sign. Use
this function to invert the sign
of the number in the active
field.
CE – Clears an editing change
and returns the contents of a
field to its previous value.
Sets the value to a unique
word for some fields. For
example, in the voltage offset
diagnostic, you may either
enter a numeric offset value
or press CE to change it to
Off.
Clear Field – Blanks the
current entry field before you
enter the desired values.
Enter – Completes the entry in an edit field. Also advances the
active field as if had been pressed (except after you edit the
wavelength on the Home screen). Press Enter to acknowledge
error messages and other prompts; the word “Enter” appears
as a cue in the lower, right-hand border of the message.
