Calibration with the RKI Four-Gas Cylinder

A specially mixed cylinder of gases is available from RKI Instruments that contains the

following mixture:

• 50% LEL methane (CH4)

• 12% O

• 25 ppm H

• 50 ppm CO

The RKI Four-Gas Cylinder is ideal for verifying or calibrating all four gas detection

ranges. The ranges can be set individually or all at once, depending upon the type of

calibration cup used.

1. Take the GX-86 to a non-hazardous environment before calibrating.

2. Turn on the GX-86 and allow it to warm-up for ﬁve minutes.

3. Adjust the Auto Zero/Span as described in “Normal Operation” on page 6.

4. Use the supplied tubing to connect the calibration cup to the regulator.

5. Attach the calibration cup to the sensor(s).

6. Screw the ﬁxed-ﬂow regulator to the gas cylinder and allow gas to ﬂow into the

calibration cup.

7. Allow adequate time for full response (1 to 2 minutes, or until the readings stabilize).

8. Adjust the COMB SPAN, O

ZERO, H

S SPAN, or CO SPAN controls as needed, so

the display agrees with the concentrations in the cylinder.

NOTE: When using the RKI Four-Gas Cylinder, adjust the O

ZERO control so the

display is 12.0%.

If you cannot set a reading to agree with the calibrating gas sample, replace the

applicable sensor.
