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.
