6.3 Error code
The instrument is equipped with the function to display various error codes.
Error codes are shown on the sub-display in a blinking state.
6.3.1 Description of error codes
Tip
z Errors and FAILs can be output as an anomaly by setting the basic setup items.
z If any error code is displayed, the transmission output is preset to the value just before the error
happens.

*1: When the calculation method for temperature compensation has been set to “No temperature calibration”, no
error is displayed since this error never arise.
*2:
You cannot recalibrate the instrument when any of the errors E21 to E24 is found. Take necessary measures
in accordance with “6.3.2 Remedies for error codes” (page 57).
*3: No contact output is generated during calibration.
