Input Specifications

The accuracy is given as ± (% of reading + counts of least significant digit (LSD)) at 23 °C ±

5 °C, with relative humidity less than 80% R.H., and after a warm-up period of at least five minutes.

Without warm-up, an additional five counts of LSD need to be considered.

[4] The positive or negative pulse width must be greater than 50 µs to enable adjustment of duty cycle or pulse width under different frequencies. Otherwise, the accuracy and range will

be different from the specifications defined.
