Interval Timing

GENERAL ORDERING INFORMATION:

Specify Meter Color & Digit Size, Meter Power and a Signal Conditioner from the list below. Specify Analog Output, Setpoint Output and Digital Interface if needed. These meters are shipped with a standard configuration and range shown below for each signal conditioner and output option type. All information for making changes is covered in the supplied Owners Manual. For other scalings or configurations, add the SC (Special Configuration) option.

DESCRIPTIONS:

The Micro time interval meter can display pulse width or time delay between individual pulses. It can also display average pulse width or average time delay between multiple pulses.

Time interval is measured between inputs on channels A and B. Timing starts when a pulse is applied to Channel A (selectable positive or negative edge), and ends when a pulse is applied to Channel B (selectable positive or negative edge). In case of a single pulsed signal, the A and B inputs can be tied together. A positive or negative slope may be selected to start timing, and the opposite slope must be selected to stop timing. Timing is achieved by counting 5.5 MHz clock pulses. Multiple integral time intervals are averaged over a gate time which is selectable from 10 ms to 199.99 s and also controls the display update time.

The Micro time interval meter uses the FR dual-channel signal conditioner board and the standard (non-extended) counter main board.
