2.1.3 Using the Unit in a other device
It is possible to use the BM-7A in a system. A system is presumed to be an apparatus in which
the BM-7A is mounted on an XY stage, and measurement is performed while moving.
When using the unit in a system, refer to the followings.

2.1.4 Reducing instrumental error between a plurality of
instruments
It is possible for the BM-7A to perform correction between a pair of BM-7A or with this
company's high-end models SR-3, SC-777, to reduce instrumental error.
There are two methods for performing correction between instruments.
・ Use optional software CM-700.
・ Use the Direct Correction function.
■ Using CM-700
In the method of using CM-700, this company's optional software, Color Master CM-700, and a
reference light source sample are necessary.
The reference light source sample should be the same kind of light source as the light source
actually being measured, and should have stable light output.
The procedure for performing correction between instruments using CM-700 is as described
below.
1
Start up the CM-700 software and select multi-control.
2
Select [Device Difference Correction] from the [Display] menu.
The screen below ([Device Difference Correction] window) is displayed.
3
Check ON the [Object] check boxes of the luminance colorimeters that are the object of
correction between instruments, and perform measurement of the reference light source
sample.
4
After all data have been collected, check ON the [Reference] check box of the luminance
colorimeter that will be the reference. Only one can be checked ON.
5
Check ON the [Object] check boxes of the luminance colorimeters that are the object of
correction between instruments.
6
Select [Instrumental Error Correction - Correction Factor Calculation XYZ] or
[Instrumental Error Correction - Correction Factor Calculation Spectroscopy] from the
[Measurement] menu according to the type of correction factor.
Measurement is performed and correction factors are calculated for the luminance
colorimeters for which the [Object] check boxes have been checked ON, and displayed in
