The Yokogawa EJA310 generates the ER07 error code during use – what’s going on?

My range is 0-20 mbar. When the value exceeds this range, the readings from ER07 and the actual value alternate in display. The full model of the transmitter is EJA310A ELS4B-82DB/KF21/D3, with a range of 0-20 mbar. During the process when the operating pressure drops from 100 to 20 mbar, the measured value and ER07 readings alternate back and forth; however, when the pressure is below 20 mbar, the readings are displayed normally. Under normal conditions, the pressure remains around 5-7 mbar
Obviously, it’s something like an out-of-range alarm, because the range you set is 0-20 mba
Yes, this ER07 is quite common; it refers to exceeding the limit. If the precision is acceptable, increase the range, such as 0-100.
