3.As the display is blinking, once the readout appears stable, press either the Δ or ∇ button to adjust the reading to coincide with the oxygen concentration of the span gas. Once set, the unit will enter Analyze Mode after approximately five seconds after the last key press.
Note: If no key presses are made during the 60 second period when the display is blinking, the analyzer will accept the display value as the true span concentration and automatically leave the span mode. The display will cease blinking.
The unit is now calibrated.
If the output of the sensor is outside of the expected range, this may be caused by:
a)Bad electrical connection between the controler and sensor.
b)Improperly analyzed or entered calibration gas value
c)Electronics failure
The unit will not accept the attempted calibration and will flash ‘0000’ on the LED display unit a valid calibration is performed.
4.7 LED Display on StartUp
When the unit is powered, it will initially display “8.8.8.8” for a short period of time. This is to confirm all LED segments are functioning. Afterward, the LED display will initiate a delay countdown, allowing the sensor’s heater to begin charging and capture a zero reading. Flowing “zero” gas or a sensor is not needed for this instrument adjustment.
