5.4.4.2 REF/SIG VOLTAGE
It is possible to check and adjust the reference voltage and signal voltage.
If the voltages have not been adjusted correctly, it may be impossible to make measurements
at a low or high temperature or measurements even in the specified concentration range may
not be made satisfactorily. (Refer to “6.5.3 ADJUSTMENT OF OPTICAL SYSTEM”.)
Although the voltages are adjusted properly at the time of a shipment, if the inside of the
instrument is contaminated because of use during a long period of time or the like, the signal
voltage may lower. Use this function to check the condition of the instrument.
