When calibrating the GX-6000 with the Auto Calibration or the Single Calibration method, the calibration gas value must be
equal to or higher than the alarm 1 setting. See “Updating the Alarm Point Settings (ALARM POINTS)” on page 145 for
instructions to change the alarm points if necessary for the desired calibration gas value.
**
Although calibrated to a specific gas, these sensors will respond to a variety of gases.
