Span reference point for calibration. Depending on the instrument calibration, the Span gas may be the same gas that the instrument is calibrated to display, or it may be another gas, which ENMET has found to have a similar response. - Page 12 Calibration of Standard Gases: Calibration of the EX-5100 should be preformed using the target gas unless Methane is known to be a possible background hazard. Reference Table 2 Standard Span Gas The EX-5100 was factory calibrated using 50% LEL levels of gases. Other levels, minimal 20% LEL, are acceptable. Contact ENMET prior to use.
