4.3 Measuring
4.3.1 General information
Depth of
immersion
For measurements in a measuring solution we recommend an immersion
depth of approx. 36 mm for optimum and reproducible measurement results.
The sensor module may only be submersed in a measuring solution up to
below the coupling ring. If it is submersed deeper, liquid can penetrate the
meter and damage it.
AutoRead
(drift control)
The AutoRead function (drift control) checks the stability of the measurement
signal. The stability has a considerable impact on the reproducibility of
measured values. The AutoRead function is automatically active. The unit of
the measured value flashes on the display as long as the stability criterion is
not met. A stable measured value is achieved when the unit of the measured
parameter no longer flashes.
Temperature
compensation
The meter has a linear and nonlinear temperature compensation (see section
4.5 S
ETTING THE TEMPERATURE COMPENSATION ). The temperature compensa-
tion can be switched off.
Reference
temperature Tref
The reference temperature (Tref) can be switched over between 20 °C and
25 °C. It appears on the display as Tref20 or Tref25. To switch over the refer-
ence temperature, see section 4.6 S
ETTING THE REFERENCE TEMPERATURE .
Caution
Special measuring media (e.g. strong acids and lyes, organic solvents) or too
high temperatures shorten the lifetime considerably or cause damage. The
warranty does not cover damage caused by such measuring media and
mechanical damage.
