5.5.2 Measuring the temperature
For reproducible pH/ISE measurements, it is essential to
measure the temperature.
You have the following possibilities for measuring the
temperature:
l
The temperature probe integrated in the probe measures
the temperature automatically
l Automatic measurement of the temperature by the
integrated temperature measuring probe of another probe
l
An external temperature probe (accessory) NTC30 or
Pt1000 measures the temperature automatically
l Measuring and entering the temperature manually.
The temperature probe that is used is indicated on the
display by
v
,
y
, or
z
.
Using the
temperature probe
integrated in the
probe
When you use probes with an integrated temperature probe,
the measured parameter and temperature are always
measured simultaneously. If the integrated temperature
probe is identified, the measured temperature value and the
status
v
appears on the display.
Using the
temperature probe
of another probe
(multi-parameter
measuring
instruments)
If no temperature probe is available for pH/ISE
measurements, the temperature can be measured by the
integrated temperature probe of another probe (oxygen
probe or conductivity measuring cell).
To do so, proceed as follows:
1 Immerse the D. O. probe or conductivity measuring
cell into the test sample.
2 Switch to the Menu mode.
3 Select the main Meas menu with
