6.1.1 Measuring the ORP
Selecting the
displayed
measured parameter
You can switch between the following displays with
<M>
:
 Voltage U [mV]
(relating to the Ag/AgCl electrode in 3-molar KCl solution)
 Voltage U
H
[mV]
(relating to the standard hydrogen electrode )
Stability control
(AutoRead )
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 display of the measured parameter flashes until
a stable measured value is available.
You can start the
Stability control
function manually at any time, irrespective of
the setting for automatic
Stability control
(see section 11.6.3) in the
System
The sensor connection and the USB-B (
USB Device
) interface are
galvanically insulated. This facilitates interference-free measure-
ments also in the following cases:
 Measurement in grounded test samples
 Measurement with several sensors connected to one
Multi 3620 IDS in one test sample
1. Connect the IDS-ORP sensor to the meter.
The ORP measuring window is displayed.
2. Check the meter with the IDS-ORP sensor.
3. Immerse the IDS-ORP sensor in the test sample.
