5.0 Operation5.0 Operation

The Gas Sampling Unit requires no calibration itself, however any sensor/transmitter or instrument associated with it

does. Follow the instructions associated with the sensor/transmitter or instrument. To insure that the calibration is

accurate with the sample draw system, you need to fill a sample bag with calibration gas.

5.1 Procedure for Sampling from Gas Bag

• Refer to Figures 6,7 and 8 for filling gas bag and attaching to Gas Sampling Unit.

• Attach the regulator to the gas cylinder. Refer to Figure 6. Use only the regulator supplied with the calibration kit.

• Attach a completely deflated gas bag (5 liter tedlar bag) to the output port of the regulator with appropriate tubing.

• Turn on the gas cylinder by rotating the knob on the regulator so gas flows into the bag. Fill the gas bag until it is

approximately 75% inflated. Close the stopcock and turn off the regulator. Remove the gas cylinder regulator and

tubing.

• Open the stopcock on the gas bag; connect the gas bag to the gas inlet port located on the Gas Sampler Unit, or the

entrance to the sensor adapter. Refer to Figures 7 and 8 for venting of calibration gas.

• Allow gas to flow for the time required for calibration of the sensor/transmitter instrument.
