communications port on the front of the unit.
The data logging capacity depends on how often the GasWatch 3 stores data and how often the
GasWatch 3 is turned on and off. The table below illustrates how much data logging time is
available for the various interval times. It assumes that the unit is only turned on once and
there are no alarms. The data logging interval time must be set using the GasWatch 3
