Operation

 

 

 

Note: If the analyzer output goes above the high alarm setpoint or below the low alarm setpoint, the display will go blank and the front panel ALARM Indicator, beneath the SET Function buttons, will blink. Hold down the SPAN button until the ALARM Indicator stops blinking.

To set the span:

1.Press the SPAN button once.

2.Within 5 seconds press either the D or Ñ button until the display is stable and matches the known span gas concentration.

The unit is now calibrated.

4.9Displaying Percent & PPM on the LED Display

The analyzer displays the concentration in percent whenever the reading is over 9999 ppm. When the reading changes to percent, the LED display will flash the oxygen concentration on and off. On the other hand, if the instrument is displaying ppm, only the concentration reading will be shown.

4.10 Supplementary Information

If, during the Span Procedure, you pressed the SPAN button by mistake, you must wait five minutes for the analyzer to resume analysis 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.

BE AWARE THAT THE ALARMS WILL BECOME ACTIVE WITHIN 5 (FIVE) SECONDS IF THE RANGE
