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 set-

ting for automatic Stability control (see section 9.5.3 A

UTOMATIC STABILITY CON-

TROL, page 72) 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

1. Connect the IDS pH sensor to the meter.

The pH measuring window is displayed.

2. If necessary, select the measured parameter with <M>.

3. Adjust the temperature of the solutions and measure the current tem-

perature if the measurement is made without a temperature sensor.

4. If necessary, calibrate or check the IDS pH sensor.

5. Immerse the IDS pH sensor in the test sample.
