Underrange/overrange of the measuring range (underrange/overrange)

• Underrange (index 0x60n0:01):
  Index 0x60n0:01 and index 0x60n0:07 (underrange and error bit) are set.
  Indicates that the output value is below -256 (approx. 0.8 % of the final value; -32767 for bipolar terminals). The output value is limited to 0 (-32768). For bipolar terminals underrange is also set if the ADC outputs the lower limit value.
• Overrange (index 0x60n0:02):
  Index 0x60n0:02 and index 0x60n0:07 (overrange and error bit) are set.
  Indicates that the output value is above 32767 (7FFF_hex). The output value is limited to 32767. Overrange is also set if the ADC outputs the upper limit value.

The error-LED lights up if the error bit is set.

Error bit (index 0x60n0:07) The error bit indicates an overrange or underrange. For the EL305x terminals (4..20 mA versions), overrange or underrange of approx. 3.5 mA is displayed.
