Criteria The AutoRead criteria affect the reproducibility of the measured values. The
following criteria can be adjusted:
high: highest reproducibility
medium: medium reproducibility
low: lowest reproducibility
7.1.2 Measuring the temperature
For reproducible ion-selective measurements, it is essential to measure the
temperature of the test sample.
You have the following options to measure the temperature:
Measurement by an external temperature sensor.
Manual determination and input of the temperature.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature measuring
mode:
If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:
3. Using <ENTER>, start a further measurement with stability control.
or
Release the frozen measured value again with <AR> or <M>.
The [AR] status display disappears. The display switches back to the
previous indication.
Increasing reproducibility also causes the response time to
increase until a measured value is evaluated as stable.

1. Measure the current temperature of the test sample.
2. Set the temperature value with <><>.

In the <ENTER>/ISE/Man. temperature menu, set the temperature value
with <><>.
