The following provides a brief overview of how to start a monitoring and
sampling run.
Before starting a run, a HEPA filter or optional 37-mm filter must be
inserted downstream of the optical assembly. The recommended 37-mm
filters are glass microfibre filters. If using the 5-micron PVC filters, use the
glass microfibre filters as a backing media when using battery power.
Equipment Damage At no time should the ADR-1500 be running without
a filter in place, otherwise serious damage to the internal components may
result.

Before initiating a measurement run it is advisable to perform the zeroing
and automatic internal check out sequences, to ensure optimal operation.

During zeroing, each range within the auto-ranging potential is used to
measure the optical background of the instrument and each value is stored
for subsequent data calculations. The duration of a Zero Operation is
usually 2-3 minutes. After Zeroing is complete, the following screen should
be present:
