2-Point calibration

You usually perform a zero point calibration for normal operation. If you prefer a 2-point
calibration for a defined small region (<0.05), you can perform this with two reference
substances whose refractive indices at the appropriate measurement temperatures are
known. The accuracy will thus be increased for this region; the measured values can be
incorrect outside this region!
The generated line equation is stored, i.e. the characteristic line of the optical sensor is over-
written. To obtain correct values for the whole refractive index region, you must reset this
line equation again (see page 12).

When a stable temperature of 20 °C
± 0.05 is reached, the calibration will last
approx. another minute.
Completion of a successful calibration is
shown in the display and by an audio
signal and is recorded.
If the calibration could not be performed
successfully, Calib. NG! appears.
The refractive index of water is now
shown.
