NOTE
The measurement resolution has a direct effect on the amount of time the
Counter requires to complete a measurement. Measurements made at the
Counter’s maximum resolution setting (1 Hz) are noticeably slower than
at lower resolutions. This is especially noticeable when the Counter is set
to average a number of measurements.
