2.2.3 Using the Instrument in Another System
When using the instrument in another system such as an XY stage, install it on the system using
the jig attachment screws on the base of the instrument.
Also, connect the instrument to a PC using the RS-232C or USB interface.
When using the unit in a system, refer to the following.

2.2.4 Reducing Error between Multiple Luminance
Colorimeters and Performing Measurement
When measuring the same measurement target using multiple colorimeters, the same
measurement results sometimes cannot be obtained because of differences in the characteristics
of each colorimeter. If this happens, perform correction for matching the values to the
measurement results of specific colorimeters.
The instrument has built-in functions for storing correction factors to memory and applying them.
These functions can be used to reduce error between multiple colorimeters.
There are 3 methods of performing correction between colorimeters as follows:
･
Use software CS-900A.
･
Use the Direct Correction function.
･
Use the correction factor function in the function mode.

Using
CS-900A
For this method, a reference light source sample is required.
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 CS-900A, refer to the [CS-
900A INSTRUCTION MANUAL].
■ Using the Direct Correction Function
When using the Direct Correction function, a RS-232C cable and a reference light source sample
are required.
Request
･
The reference light source sample should have stable light output and be the
same type as the light source actually being measured.
･
To use the Direct Correction function, the RS-232C parameters of the 2
luminance colorimeters must be the same.
When using the Direct Correction function, first, measure the light source using the reference
instrument, and write that measurement data to the BM-5AC to be corrected.
