Residual uncertainty (approx. two standard deviations) after internal temperature correction taking into account the temperature characteristic of the sensor and its temperature. The specified temperature
effect does not apply to the frequency ranges specified in footnote 11 (page 10).
Black curve:
Zero offset (within 1 h after
zero adjustment; temperature
variation <1θC; meter with
probe run in for about 2 hours)
