Compatibility With MiniLaz Buttons
The Lasair II particle counter is compatible with MiniLaz TouchRAM buttons, but
there are some differences. In general, buttons written by the MiniLaz can be used
by the Lasair II particle counter. When a Lasair II particle counter format button is
scanned by a MiniLaz, it is ignored.
MiniLaz buttons have the following characteristics:
• MiniLaz buttons support the first five channels of particle alarms, but do not
support particle alarms on the Lasair II particle counter’s largest channel.
• Particle alarms in metric units written by the MiniLaz cannot be converted to
meaningful particle counter alarms.
• MiniLaz buttons support temperature and rh alarms, but not user analog channel
alarms.
• MiniLaz buttons can read the Particle Measuring System address.
Comparison to MiniLaz Buttons
The Lasair II particle counter button format offers the following advantages over a
MiniLaz button format:
• Location names may be 16 characters rather than 7 characters.
• The purge delay time is recorded.
• The time-of-day start option is recorded.
• The Sample by Volume/Sample by Time setting is recorded.
• Alarm buzzer on/off is recorded.
• Differential particle alarms may be used.
• Supports Print Sample Average feature.
• Support for network parameters.
