within the monitored time interval.
The minimum duration until a measured value is assessed as stable is the
monitored time interval. The actual duration is mostly longer.
Freezes the mea-
sured value (HOLD
function)
With the HOLD function, you can freeze the current measured value. The dis-
played measured value stops changing until you switch the HOLD function off.
6.1.2
Measuring the temperature
For reproducible pH measurements, it is essential to measure the temperature
of the test sample.
You have the following options to measure the temperature:
Automatic measurement of the temperature with the temperature sensor
(NTC30 or Pt1000) integrated in the sensor.
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:
Measured
parameter
Time interval
Stability in the time interval
pH value
15 seconds
Δ
: better than 0.01 pH
Temperature
15 seconds
Δ
: better than 0.5 °C
1.
Freeze the measured value with

.
The [HOLD] status indicator is displayed.
2.
Release the frozen measured value again with
<HOLD>
.
The HOLD function is switched off.
The [HOLD] status display disappears.
