Electronics Temperature (ET) upper
operating limit from specification.
Units are same degree units as has been
selected for SV (Secondary Variable).
None.
Actual limit used in "Time Above Limit" and
"Time Since Last Event". Value is equal to
"Max ET Limit" less 10% of limits range.
Electronics Temperature range is -40F to
185F for a total of 225F.
ET Upper Stress Limit= 185F - 10% of
225F = 162.5F.
None: calculation is automatic.
