The Stability control function checks whether the measured values are stable
within the monitored time interval.

Temperature
The minimum duration until a measured value is assessed as stable is the mon-
itored time interval. The actual duration is mostly longer.
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.
1. Freeze the measured value with
The [HOLD] status indicator is displayed.
2. Release the frozen measured value again with
The HOLD function is switched off.
The [HOLD] status display disappears.

Measuring the temperature

For reproducible D.O. measurements, it is essential to measure the tempera-
ture of the test sample.
The temperature is automatically measured by the temperature sensor
(NTC30 or Pt1000) integrated in the sensor.
