4.7Displaying Percent & PPM on the LED Display

The analyzer displays the concentration in percent whenever the read- ing is over 9999 ppm. When the reading changes to percent, the LED display will alternate between flashing “PC” and the oxygen concentration. On the other hand, if the instrument is displaying ppm, only the concentra- tion reading will be shown.

Supplementary Information

If, during the Span Procedure, you pressed the SPAN button by mis- take, you must wait five minutes for the analyzer to resume analisis or you can press the UP button and then the DOWN button. (Pressing the UP and DOWN buttons causes the analyzer to time-out in five seconds instead of five minutes).

If during the span procedure, you press the RANGE or ALARM buttons:

-either the range or alarm routine will be activated.

-any changes to span will be rejected.

-the 60 second alarm delay will not occur, i.e., the alarms will be responsive immediately.

CAUTION: TET/AI considers the action of pressing the ALARM or RANGE buttons to be at your (the user’s) discretion. The user should be

aware that the alarms will become active within 5 (five) seconds if

the Range or Alarm bottons are pressed during Span. This may result in false alarms if the Span gas has not been fully purged from the Cell and Sample lines.
