OUNDATION
The table below shows a summary of error messages for BRAIN and HART protocols.

*1: This error code appears at a capsule problem or when an illegal overpressure is applied to the pressure sensor.
*2: If the normal pressure is regained, the Er.01 will disappear according to the setting of the parameter of E50 AUTO RECOVER.
When the E50 AUTO RECOVER is set to ON, the Er.01 will disappear automatically. The default setting for this parameter is
ON. When the E50 AUTO RECOVER is set to OFF, restart the transmitter to cancel Er.01. If no error code appears then, perform
necessary adjustments such as zero-adjustment to continue the operation. If the error code still appears, 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.
