17.4 How to Set the Instrument Constant Value
To set the Instrument constant which is obtained in Section 17.1 “Check and adjusting of instrument
constant”, follow as below.
Note: Each of the Prism mode and Non-prism mode has instrument constant.
You must check the instrument constants in each mode and obtain the instrument constants
of Prism mode and Non-prism mode.
● If you reset the instrument constant of prism mode ( Prism-long), you must vary the prism
constant (Prism-short) by the same quantity as the amount of increase or decrease of the
instrument constant of the prism mode.
● If you reset the instrument constant of non-prism mode ( Non-prism-long), you must vary the
prism constant (Non-prism-short, Non-prism-middle) by the same quantity as the amount of
increase or decrease of the instrument constant of the non-prism mode.
