OPERATION
3-1 OVERVIEW
It is recommended that the operator read the
entire manual through before first operating
the instrument.
The operator can generally operate the Model
7003M using the flow chart in Figure 3-2 on
page 3-2 after the display symbols and modes
of operation are understood.
3-2 KEYPAD OPERATION
During each particular keystroke sequence,
the analyzer will recognize only certain keys.
If an unrecognized key is pressed, the
instrument will either not respond or will
display "SrY" ("Sorry") and return to RUN
Mode.
Generally, to escape from any routine, press
ENTER repeatedly until the instrument returns
to the RUN Mode and the oxygen
concentration is displayed.
Changing Parameters With The Keypad
All operation parameters are set with the
keypad. When the instrument is waiting for
operator input, the display will flash a digit. At
this point, if the number itself can be changed,
the operator can generally increase the
number (UP arrow) or decrease it (DOWN
arrow) at this time. An exception is when the
operator is restricted to pre-selected choices
(e.g., output current ranges, see Section 3-5b
on page 3-13).
When changing a value, an arrow key can be
pressed for a moment, and the display will
change by one digit. If it is held down, the
display will change, slowly at first, then
rapidly.
If the display has a digit flashing and will not
change, check the range of that parameter.
For example, an alarm setpoint cannot be set
higher than 25%.
When the number desired is displayed, press
ENTER. The Model 7003M will accept that
number and continue with the next step of that
routine.
