4.5 Selecting a Fixed Range or Autoranging

The Model 3300ZB can operate in fixed high, fixed low, or auto- ranging mode. To change modes:

1.Press and then release the SET HI RANGE and the SET LO RANGE buttons simultaneously.

2.Within 5 seconds press either the Δ or ∇ button until Auto, Lo, or Hi displays on the LCD, as desired.

After about three seconds, the analyzer resumes monitoring in the selected range mode.

4.6 Calibration

Power up the analyzer and allow the LED reading to stabilize. Wait at least ten minutes after powering, giving the heater and bias voltages enough time to reach operating voltage. Set the alarm set-points and the full-scale ranges to the desired values.

Procedure:

1.Apply calibration gas of a known concentration. A span gas containing an oxygen content of 60-100% of the range of the analyzer is recommended.

Note: If the analyzer output goes above the high alarm set-point or below the low alarm set-point, the front panel ALARM Indicator located beneath the SET function buttons will blink. When the SPAN key is pressed, the alarm indicator will stop blinking.

2.Press the SPAN button once. The value on the LED display will blink for 60 seconds while the display tracks the O2 concentration in the span gas.
