8.1 Preliminary checks before taking readings (best practice)
Prior to use, it is good practice to ensure
that:
Step 1 If using GAM ID codes and
information have been uploaded
from GAM to the analyser. Please
see section 8.1.1 for more
information on this.
Step 2 The instrument has the correct
time and date set.
Step 3 The water trap filter is fitted and
is clean and dry.
Step 4 The battery has a good charge
(minimum 25% charge, even if
only a few readings are required).
Step 5 All gas channels have been
zeroed, without gas concentration
present.
Step 6 If necessary check the span
calibration with a known
concentration calibration gas.
Step 7 Take readings.
