Next, place the BM-7AC to be corrected in the location where the reference instrument placed,
and measure the same light.
A correction factor is calculated for the BM-7AC to be corrected based on the data of the
reference instrument, and the data of the BM-7AC to be corrected.
The procedure of measurement for correction between instruments using the Direct Correction
function is as explained below.
1
Set beforehand the data output method and communication method for the reference
instrument in reference to the table below. Then connect it with the BM-7AC to be
corrected using a specified cable. Also, set the RS-232C parameter settings of the BM-
7AC to be corrected are the same as those of the reference instrument.
2
Set dip switch 5 of the BM-7AC to be corrected to the FACTOR B side, and turn ON the
power.
3
Turn on the power to the reference luminance colorimeter.
4
The BM-7AC to be corrected changes to the function mode, and the [*Direct-Correction
Factor*] screen is displayed.
