The Display Group has controls to select the display mode and to
select if the display shows measurement or gate time readings.
In normal mode, the counter is armed to receive signal at the trigger

duration as programmed with the Gate Time parameter, processes
the result, displays the reading and continues with the same
process as long as the signal is available at the input.
In hold mode, the counter is armed to receive signal at the trigger
input. When signal is sensed, the gate to the counter opens for
duration as programmed with the Gate Time parameter processes
the result, displays and holds the reading until the next Reset/Arm
command.
To display and modify the gate time parameter, click on the Gate
Time LED and modify the gate time per your requirements. Gate
