Test Dialog: This window enables you to test your
calculation after the recorder has compiled it. The
original calculation is shown in the top line. There
are entry boxes to enable you to set actual values for
the channel variables. Once you have entered data,
pressing the Calculate button will display the
answer in the line above it. This test dialog
can also be used to evaluate functions or
any other expression entered.
If the answer is as expected or you need to go back
and alter the formula press the Exit button.
MIN MAX AVG RESET: If the Min, Max or Avg
function is used in an equation, upon exit you will
get the Min, Max, Avg Reset Dialog window shown
right. This enables the Min, Max or Avg values to
be reset periodically, upon an external event or
upon an alarm event.
Auto Reset Enable: If this box is unchecked the
Min, Max, Avg will calculate continuously unless

set time. This allows the user to synchronize the reset to a known time. This also allows several channels
to be synchronized together if the Reset Sync time is set to the same for all. This time is ignored if the
enable box is not checked.

alarm/event log each time the values reset.
