3.Immediately (within 5 seconds) press either the Δ or ∇ button until the display is stable and displays the oxygen concentration of the applied calibration gas. Once set, the unit will enter Analyze Mode after approximately three seconds.
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 control and analysis unit
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.
