7.Press the Enter button and the display will read 10 alternating with the gas, mE, Pro or Hy (blinking), indicating the sensor is looking for gas.

8.Start applying gas to the gas sensor.

Note: The sensor will look for the gas for 45 seconds. If no gas is applied or detected in that time, the display will return to CAL.

9.When the sensor detects the gas, the display will flash back and forth between the gas concentration and SPn and the calibration will progress. The display will show this for a maximum of 165 seconds.

10.When the calibration is successful, the display will flash back and forth between 10 and PAS.

11.Remove the gas. The display will return to “SPn”, then normal mode. The calibration is done.

12.If the calibration fails, the display will flash back and forth between the gas concentration and FAL (fail). If this occurs, check the pressure gauge on the regulator. If the pressure is less than 25psi the flow of gas may not be adequate to properly calibrate the unit. If there is proper pressure in the cylinder repeat steps 4 through 11. If the unit fails to calibrate twice contact 3M Macurco Technical Assistance at 1-800-237-9049.

13.Disassemble the cylinder and regulator.

14.Re-assemble the 3M™ Macurco™ GD-6 Combustible Gas Detector (make sure the LED is aligned with the hole in the front case).

15.See Calibration Flowchart.
