Underrange, Overrange

Undershoot and overshoot of the measuring range (underrange, overrange), index 0x60n0:01, 0x60n0:02

Chapter Data stream and correction calculation contains a clear description of the correction calculation between the raw values and the output values if the limit ranges are exceeded.

The underrange bit is set if, based on the raw value, a value of 0x1300 is undershot by 1 bit.

The overrange bit is set if the value of 0x7FFF is exceeded by 1 bit.

Underrange, Overrange 1:

Error bit (index 0x60n0:07), Error LED

The Error bit and the Error LED are set if, based on the raw value,

a value of approx. 0.5 mA below 4 mA is undershot or

a value of approx. 0.5 mA above 20 mA is exceeded.

  • This prevents the triggering of the Error LED if the sensor transmits a little more than 20 mA.
