4.0 CALIBRATION

4.1 Calibration Notes

The instrument was calibrated and tested prior to leaving the factory. Therefore, it is possible to

use the instrument directly out of the box. Under normal conditions, recalibration is

recommended once every 6 months. For a two point calibration, the first point is typically Zero

(clear air); the second point (also called span) is a determined gas concentration value.

If the preset EC-Gold Dual calibration span value is known and you have the same calibration

gas concentration, the entire calibration procedure can be completed without removing the front

cover.
