• TRIGGER
Enable, the operator may enable or disable the TRIGGER function.
If Enable is OFF the enabled archives store the measures with the
relative rate, all of time.
If Enable is ON, the enabled archives store the measures with the
relative rate only after the receiving of a pulse on digital input 2 (DI2). The
storing will be active for the set time in Time-min. If there is no enabled
archives the trigger function has no effect.
Time-min. defines when the storing time is active.
With a logic level 1 (voltage present) on the digital input 2 (DI2) the timer relative to Time-min will be
reset and the storing enabled. Only when the signal go down, the counting starts. The range is
1÷9999 minutes and the default value is 60 minutes.
No congruent set between TRIGGER storage enabled and Type of the
digital input will involve the visualization of the warning message on the
display (see for example in this figure). An affirmative answer will enable
the TRIGGER function and the setting of the digital input will be set to Not
Used.
If any of the above mentioned parameters relative to MINMAX, AVG.POW.

memory with no residual information’s.

protocol does not come deleted and for this reason it’s possible to recover
