Prior to use, it is good practice to ensure
that:
Step 1 If using LSGAM - all necessary ID
codes and information have been
uploaded from LSGAM to the
analyzer. Please see section 8.1.1
for more information on this.
Step 2 Check the ‘Mode of Operation’ is
correct. Choose either GEM5000
for gas extraction monitoring
analyzer or GA5000 for landfill gas
analyzer. Change using ‘Special
Actions’.
Step 3 The instrument has the correct
time and date set.
Step 4 The water trap filter is fitted and
is clean and dry.
Step 5 The battery has a good charge
(minimum 25% charge, even if
only a few readings are required).
Step 6 The gas channels have been
zeroed, without gas concentration
present.
Step 7 If necessary check the span
calibration with a known
concentration calibration gas.
Step 8 Take readings.
