# Run Timeout

As you configure an OCVMax tool you can set a run timeout value, which determines the amount of time, in milliseconds, the OCVMax tool is allowed to return the best result for the verified character keys in your string(s).

The OCVMax tool considers the run timeout value in any attempt to locate and verify each character key in the string. Most strings will fail verification if the run timeout value is too small. If you allow the OCVMax tool to tune itself with good values for various search parameters, the tool will generate a good starting value for the run timeout.

In addition, although a string can pass verification with a particular run timeout value, enabling a larger run timeout value can generate more accurate search scores for each character key in the string. For some images, more accurate search scores can mean the difference between a verified character string and one that fails verification. In general, you should use as large a run timeout value as you can allow for each inspection of your vision application.

In some cases an OCVMax tool can return a successful result while exceeding the set run timeout value. If your vision application requires that the OCVMax tool complete its analysis within a specific time allotment, set the run timeout value to a few milliseconds less to accommodate for this type of situation.
