Gas calibration
The measuring range of model RX-415 is dual expanded scale of 0-100%LEL and 0-100vol%
for HC, and 0-25vol% for O2. Then, the gas calibration for all ranges is required.
(1)
Prepare the calibration gas (both for low density gas and high density gas) and sampling bag.
(2)
Remove the filter tube and gas sampling tubes from the instrument. Then, arrange to connect
sampling bag from the gas inlet of instrument.
(3)
Turn on the power and make zero adjustment.
(4)
Put the calibration gas

sampling bag and make gas calibration in the following procedure.
