Check input.
*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(defalut setting), the Er.01
will disappear automatically. When the E50: AUTO RECOVER is set to OFF, restart the transmitter
to cancel Er.01. If no error code appears then, perform necessary adjustment such as zero-adjust-
ment 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.
