Special functions:
The AutoRead function checks the stability of the measurement signal (ex-
cept for the measurement of the ORP voltage). Activate AutoRead with
<AR>. Press <RUN/ENTER> to start the AutoRead measurement. During
the AutoRead measurement, AR flashes on the display until a stable mea-
sured value is reached. This can be terminated at any time taking over the
current measured value with <RUN/ENTER>.
There are several measuring ranges available for conductivity measure-
ments. If a measuring range is exceeded, AutoRange causes the measuring
instrument to change automatically to the next measuring range. When the
AutoRange function is switched on, ARng appears on the display.
The measuring instrument automatically measures the temperature of the
sample with the integrated temperature sensor of the conductivity measuring
cell (display TP). In measuring cells without temperature sensors, the tem-
perature can be entered manually with <L> <M>.
The factor for determining the dry filtrate residue is freely selectable in the
range 0.40 to 1.00. TDS is also displayed in the measuring mode as well as
the measured value. The factor can be changed if necessary with <L> <M>.
You can select from the following settings:
! Nonlinear temperature compensation (nLF) according to EN 27 888
! Linear temperature compensation (Lin) with selectable coefficients of
/
0.001 ... 3.000 % K
! No temperature compensation (- - - -)
Press <CAL> until tc appears to set the temperature compensation. Then,
confirm with <RUN/ENTER>. Select the required option with <CAL>.
If necessary, select the temperature coefficients with <L> <M>. Return to the
measuring mode with <M>.
