3.5.3 Rate
The RATE operation sets the integration time of the A/D converter, the period of time the
input signal is measured (also known as aperture). The integration time affects the usable
digits, the amount of reading noise.
The RATE items are explained as follows, you can press Rate key to choose.
Fast： 55 readings/s. Use FAST if speed is of primary importance (at the expense of
increased reading noise and fewer usable digits.
Medium： 25 readings/s. Use Medium when a compromise between noise
performance and speed is acceptable.
Slow： 3 readings/s. SLOW provides better noise performance at the expense of
speed.
