BE6020-14 1316A-1 Multi Gas Monitor LumaSense Technologies A/S
Instruction Manual Page 67 of 98
Figure 4.11.The particle filterDS2306
The particle filter is attached to the rear panel of the monitor.
Dismantle the filter from the luerlok fittings and replace it with a new
DS2306.
4.3.3 Calibration Gases
To perform a full calibration gases are required.
Special gas mixtures containing known concentrations of
Hydrocarbon (Propane or Hexane), Carbon Monoxide and Carbon
Dioxide are required to span calibrate the VM0100A
If UA1372A is mounted with electrochemical sensors O
2
(VM200A)
and NO (VM0201A) then calibration gases to span calibrate the
sensors are also needed.
The gas mixture shown in Table 4.1 is allowed concentration ranges
for calibrating the monitor
Gas Concentration Range
Propane 100 ppm to 6 %
Hexane 50 ppm to 3%
Oxygen 1% to 25 %
Carbon Dioxide 1 % to 20 %
Carbon Monoxide 0.5% to 15 %
Nitrous Oxide 100 ppm to 5000 ppm
Nitrogen Balance

4.3.4 Connecting the Calibration Gas
Warning! Never make a direct connection from the pressure valve
on a gas cylinder. Always use a side-stream connection like the one
shown in figure 4.12.
