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 obtain the instrument constant of prism mode. If you reset the instrument

constant of the prism mode, you must vary the non-prism constant (Non-prism-short, Non-

prism-long) by the same quantity as the amount of increase or decrease of the instrument

constant of the prism mode.
