Page 10: Calibration Method
Make sure the instrument is in clean air environmrnt (do not do this in a non-clean air environment). Note: After the zero point calibration, the instrument reading will automatically return to zero (oxygen 20.93% VOL, nitrogen 78.1% VOL, carbon dioxide 450ppm). Power on when ready. www.gasdog.com +86 773-280-9002 sales@gasdog.com... - Page 11 This operation is mainly divided into two steps: [Set Calibration Point] and [Span Calibration]. Note: After the calibration, please remove the calibration cap. Do not install the calibration cap on the detector during testing.
