Failure to Read Characters

Failure to Read Characters during Teaching
• The read results may be unstable if the contrast is low. Adjust the brightness to improve the contrast.
• The characters may not be in the measurement region. Check to see if the measurement region is set correctly.
• The specified character format may not agree with the format of the read characters. Check the character format.

Reading a Variable Length Character String

Set the reading mode in the measurement parameters to [Variable]. The character format should be the same
as the maximum character string length format.
