WAit
Wait Time
Define a “waiting time“, this is the time expressed in

to the next, before it sets the display to zero. When
you enter “0“, the unit will wait forever and show the
last result until it receives the next input.
0.1 … 99.9 sec 1.0
The setting of this parameter automatically limits the minimum

the unit will respond to frequencies > 10 Hz only and all lower
frequencies will just display 0.
