*1: For Model EJA510A and EJA530A, this error code appears when an illegal overpressure is
applied to the pressure sensor in addition to the capsule problem. The Er. 01 will remain even if
the normal input pressure is regained.
*2: For Model EJA510A and EJA530A, restart the power to the transmitter. Then if no error code
appears, perform necessary adjustments such as zero-adjustment to continue the operation.
If the error code still exists, replace the capsule assembly.
*3: For Model EJA120A, static pressure cannot be measured. The display is always 0 MPa, but this is
not a measured value.
