Adjustment

6-1 Creating Reference Data

The reference data is necessary for adjustment: The adjustment program will not operate normally
without it. Before adjustment, be sure to create the reference data, using the same model (with
normal camera block) as the one to be adjusted.
Information:
1) The reference data is used to reduce the difference between environments of servicing site and
factory (color temperature of light box, etc.). Using the reference data will increase adjustment
accuracy.
2) The reference data is usually created once for each model because it is recorded on hard disk
drive (HDD) of PC with the adjustment program. However, creating reference data again is
necessary in the following cases:
a) When performing adjustment using a light box that is different from that used when the
reference data was created.
b) When performing maintenance of the light box used when creating the reference data
(replacing fluorescent light, etc.).
c) When performing adjustment using a C12 light balancing filter that is different from that used
when the reference data was created.
d) When deleting the folder containing the adjustment program from HDD.
Restrictions:
If the same model with normal camera block as the one to be adjusted is not available, the reference
data can be created by the following procedure. However, reference data created this way has been
prepared at the factory, assuming the environment of service workplace, and may not be suitable
for all service workplaces. Therefore, it is recommended that you create reference data using the
same model with normal camera block as that to be adjusted.
1) Store the adjustment program on HDD, referring to "6-1-5 Copying or Deleting Adjustment

Program".

2) Start up Explorer and open the refdata folder in map05w folder.
3) Refer to the following table to check the reference data file name of the model to be adjusted.
4) Copy the file with the same name as the reference data file name checked in step 3) in refdata
folder to map05w folder.
