Stability control
(AutoRead)
& HOLD function
The stability control function (AutoRead) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc-
ibility of measured values.
The measured parameter flashes on the display

as soon as the measured value is outside the stability range
 when the automatic Stability control is switched off.
You can start the Stability control manually at any time, irrespective of the
setting for automatic Stability control (see section 10.6.3 A
UTOMATIC S TABILITY
CONTROL , page 96) in the System menu.
The sensor connection and the USB-B (device) interface are gal-
vanically isolated. This facilitates interference-free measurements
also in the following cases:

Measurement in grounded test samples
 Measurement with several sensors connected to one
MultiLab 4010-2 in one test sample
IDS ORP sensors are not calibrated. However, you can check IDS
ORP sensors using a test solution.
1. Connect the ORP sensor to the meter.
The ORP measuring window is displayed.
2. Adjust the temperature of the solutions and measure the current tem-
perature if the measurement is made without a temperature sensor.
3. Check the meter with the ORP sensor.
4. Immerse the ORP sensor in the test sample.
