The D-Guard² is factory calibrated before dispatch. You must calibrate the D-Guard²
regularly. Calibration adjusts the response of the D-Guard² to known concentrations of
gas at two points, zero and span.
Zero calibration uses zero-grade air or fresh air, which does not contain any trace of
the detectors intended target gas. You can set the concentration of zero calibration
gas. See section 18.4 .
Span calibration uses a known concentration of the intended target gas. You can set
the concentration of span calibration gas. See section 18.3 .
