Calibration
To calibrate the 319R:
1.Place the power switch in the ON position.
2.Allow the LCD reading to stabilize.
3.Expose the sensor to ambient air (20.9%) or instrument grade air. If the analyzer goes overrange, the display will go blank and the LED to the left of the display will blink. Hold down the SPAN button until the LED stops blinking.
4.While holding down the SPAN AT 20.9% button, adjust the potentiometer to the right of the button until the display is stable and reads 20.9%.
5.Release the button. The unit is now calibrated.
6.The alarms will be disabled for about 25 seconds after the SPAN button is released. Disabling the alarms allows air to be purged from the sample system without tripping any alarm set below span, or 21%.
NOTE: Do not attempt to adjust any alarm setpoints while the alarms are disabled during the
