F
ilter Entry – Stepwise or Free Entry. (Not applicable to the ROUTE module.) When
high / low pass filters are required for a module’s measurement setup, determines
whether the filter frequency parameter is entered from pre-defined options (i.e., from a
drop down list) or as numeric input (i.e., typed into a numeric entry field).
Stepwise – Filter frequency parameter is selected from pre-defined options.
Free Entry - Filter frequency parameter is typed into a numeric entry field.
Allows you to set a more precise filter parameter.
Trigger – User or Automatic. Specify whether the trigger level is set automatically by
the Microlog, or by the user (during the setup of module measurements that require a
trigger or, for ROUTE data collection, with the Instrument Configuration screen’s
Trigger settings).
Automatic – The Microlog examines the trigger signal and automatically sets
the trigger level to the signal’s mid-point. This delays acquisition slightly, but
allows the unit to trigger from a variety of sources.
 If set to Automatic, the Analyzer mode’s User / Trigger Level
setting reads “Automatic” and cannot be set.
User – The trigger level is set by user specified settings (either in appropriate
module setup menus or, for ROUTE data collection, from the Instrument
Configuration screen). Reference the following Global Measurement
Settings section for details.
Ext trig slope - + or -. Set the trigger edge, either +ve for a rising edge, or –ve for a
falling edge.
