Undershoot and overshoot of the measuring range (under-range, over-range), index 0x60n0:02, 0x60n0:03

Undershoot:
Index 0x60n0:01 and  index 0x60n0:07 (under-range and error bit) are set.
Indicates that the output value is below -256 (approx. 0.8% of end 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.

Overshoot:
Index 0x60n0:02 and  index 0x60n0:07 (over-range and error bit) are set.
Indicates that the output value is above 32767 (7FFFhex). 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.

Undershoot and overshoot of the measuring range (under-range, over-range), index 0x60n0:02, 0x60n0:03 1:

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.
