Hi or Lo Multi-Point Calibration
Up to three gas concentrations (cal-points) for each range may be calibrated to using the
following steps. Three cal-points will give the most accurate readings over the entire
range. The Calibration process is sequential and will only work properly if all steps are
followed in order. The examples below use the Lo Multi-Point Cal screens, but the
procedure is the same for the Hi Multi-Point Cal screens.
