Readout Key Timing
Several keys on the Readouts have multiple functions.
How long a key is pressed is important since the function executed when a key
is pushed is dependent on how long it is pressed.
This manual uses the term “
Momentarily
” to describe a key press of less than .8
seconds, and
“Press and Hold ” to describe a key press of longer than 1
second.
For
Momentary key press operations, the Function is executed when the key is
released.
For
Press & Hold operations, the Function is executed after the key has been
pressed and held for the prescribed amount of time.
See the chart below for a summary of the functions performed by the keys below:
