Appendix 2 - Duration and Interval Table for Logging
Pre-triggers
are only available with fast recording times and when a trigger of
sensor rises
or
falls
below
has been set.
For very fast sample rates there is a limit to the number of sensors that can be connected, this is
indicated in the maximum sensors column. For slower rates the internal temperature sensor and up
to six external sensors can be used.
The following
