Tips
• In the "Solution/Error cancellation method" column, "RS" denotes an RS232C command
and "I/O" denotes an external HOLD signal.
• The error output format of RS-232C is "CH**,Error$$CRLF".
• "Error 40" (Linear Gage malfunction) is displayed even when no Linear Gage is
connected.
• "Error 90" and "Error 95" are displayed when a tolerance value setting error occurs due to
a key operation.
• "Error_90" in the RS-232C output means that a tolerance value setting error has occurred
due to an RS command.
• If an error occurs while you are setting parameters, the Preset value, or the tolerance
value, the error will be displayed after you return to the counter state. However, the error
signal will be output immediately to any external output.
