RKI Instruments Gas Tracer 10,000 ppm - Manual (Page 105)

10,000 ppm Gas Tracer Operator’s Manual Preparing for Calibration or Bump Test • 98
To calibrate or bump test the Gas Tracer, you will need:
• Known calibrating sample of ppm methane gas.
• A gas collection bag with hose clamp
• A 0.5 LPM fixed-flow regulator or dispensing valve
• Non-absorbent tubing
• 6 inch humidifier tube
Preparing for Calibration or
Bump Test
Perform the following tasks prior to performing a calibration or a
bump test.
Normal Operation Fresh Air Adjustment
Whether you will calibrate the Gas Tracer or perform a bump test, you
will need to set the fresh air readings first.
1. Find a fresh air environment. This is an environment free of toxic
and combustible gases and of normal oxygen content (20.9%).
2. Turn on the unit as described in “Turning On the Gas Tracer” on
page 16. Use the sample hose and probe.
3. With the unit on, perform a fresh air adjust by pressing and
holding the AIR▲ button. The display prompts you to hold the
AIR▲ button.
4. Continue to hold the AIR▲ button until the display prompts you to
release it. The Gas Tracer will set the fresh air reading.
Filling the Gas Bag
Use the following procedure to fill the gas bag with either zero air or
ppm calibration gas.
1. Slide the tubing clamp onto the tubing and connect the tubing onto
the sample bag’s inlet. Leave the clamp unclamped for now.
