Press ENTER on the front panel cursor keys, then the function key. The display will show which
gas readings will be measured, i.e. Natural Gas, Light Fuel Oil, etc. To change from a different
desired fuel from this, go to MENU/SETUP/FUEL TYPE.
8.
The display will prompt for ’GO'. Press the F3 key. The display will show gas readings.
9.
Insert probe into the sample measurement point.
10. To switch the instrument off, remove probe from sample point, press and hold the ON/OFF but-
ton for approximately 2-3 seconds. The instrument will purge the gas sensors with fresh air for
30 seconds, then completely shut down.
Probe Insertion:
Loosen the support cone on the probe to allow free movement. (See Description of
Instrument).
The probe should be inserted in to the sample area carrying the gas flow through a 11mm to 16mm /
7/16” to 5/8” sampling hole.
The probe insertion length can then be adjusted and the support cone re-tightened when the tip of the
probe is in contact with the main stream of the gas flow. The thermocouple measurement reading
may assist in determining the best position.
Avoid the infiltration of air at the sampling point.
Static Discharge - refer to Section 1.3, Page 5 for details.
High Gas Concentrations:
Measurement periods are only restricted by the concentration of the
gases being measured. i.e. Low concentrations in 10 or 20 ppms will not effect the continuous opera-
tion. High concentrations in 10,000 ppms will quickly saturate the sensors.
Water Catchpot:
The other limiting factor of the sampling period is water filling the catchpot. The
catchpot should be periodically checked and emptied before it overflows into the pump.
To empty the water catchpot.
1.
Unclip the container and pull out the bottom.
The container is hinged at the top and must not
be over extended, more than 45°.
2.
Unscrew the catchpot, remove and empty out water.
Replace in reverse and ensure the catchpot makes a good seal.
Do not over-tighten.
Air leakage will
cause errors in gas readings.
3.
Make sure O-ring seal is in place prior to replacing water catch-pot.
