To set the Instrument constant which is obtained in Section 17.1 “Check and adjusting of instrument
constant”, follow as below.

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.
