3-12 49iQ Instruction Manual
The Calibrate Span Coefficient screen is used to enter the span
concentration and calibrate the O
calculated, stored, and used to correct the current reading.
The following screens are shown in single range mode and dual or auto
range mode. In dual or auto range modes, "High" or "Low" is displayed to
indicate the calibration of the high or low coefficient. The Calibrate High
Range Span Coefficient and Calibrate Low Range Span Coefficient screens
function the same way.
It is important to note the averaging time when calibrating. The longer the
averaging time the more precise the calibration results. To achieve
maximum precision, allow the instrument to stabilize each time input gas is
changed and set the averaging time to 300-second averaging.
