Request For Service Options for the OMRDATA Scanner Program

The only information used from this grid is the "Highest Question No. Used." The value to be entered here indicates the length of each data record which may range from 1 to 180. 

The Main Parameters are used to communicate the following information to the OMRDATA scanner program (please write the number in the box provided and fill in the corresponding bubble to request each of the desired actions). Note that the OMRDATA sheet is arranged as 4 sets of grids with each set allowing the coding of up to 45 characters. The sheet may be treated as a single entity yielding one data record, or it may be divided into a top half and bottom half yielding two data records per sheet, or each of the 4 sets of grids may be treated separately yielding four data records per sheet.

A. Number of data records per sheet:

1 = 1 record/sheet allowing up to 180 characters per record
2 = 2 records/sheet allowing up to 90 characters per record
4 = 4 records/sheet allowing up to 45 characters per record

B. Identification number:

0 - 9 = number of columns to check for presence of blanks at the beginning of each record

C - F are not used.

The Secondary Parameters are used to communicate the following information to the OMRDATA scanner program (please write the number in the box provided and fill in the corresponding bubble to request each of the desired actions):

K. Check for multiple responses to an item:

0 = pocket (or flag) sheets that have multiple responses to an item
1 = change multiple responses to blanks
2 = use * to indicate a multiple response

L. Check for omits on sheets having a high percentage of light marks:

0 = don't check
1 = pocket (or flag) sheets having omits along with too many light marks

M. Tolerance value for percentage of light marks:

0 - 9 = first digit of percentage of maximum percentage of light marks (the value 3 is recommended).

NOP. Minimum number of marks that should appear in each record:

This 3-digit value gives a lower limit for the number of marks that should appear on an answer sheet. Sheets having less than this number are rejected for visual inspection (if the 'Pocket Sheets' option has been selected). This option is used to guard against the possibility that too many marks are treated as erasures as a result of the option selected for 'M'.
 


One of these two options must be chosen. If you request "Pocket Questionable Sheets for MANUAL Verification", sheets that are rejected because they appear to be improperly completed (for reasons such as those requested in the Secondary Parameters above) will be diverted to a special hopper where the operator can review the sheet to see if it can be repaired. After any possible repairs are made, the rejected sheet is scanned again and forced to be accepted even if repairs cannot be successfully performed.

If you request "FLAG Questionable Fields and Process as if Normal", sheets that appear to be improperly completed will not be selected for operator attention. Instead, a '?' will be placed at the beginning of the field that contains questionable results. Choosing this option means that the sheets will be processed without operator assistance, e.g., a sheet which has been completed using pen instead of pencil will be accepted as though it was completely blank.


None of these menu items normally applies to data obtained from OMRDATA sheets. We automatically run a program that takes the output from the scanner and creates a simplified data file. An output file with the suffix ".dat" is created which contains the desired data records. In particular, if a data sheet contains more than one record, the ".dat" file contains the individual records.


As the heading implies, this option does not apply to the OMRDATA scanner program.
