1.2.2 IDS adapter for analog sensors
With the aid of an IDS adapter, you can also operate analog sensors
on the Multi 9420. The combination of the IDS adapter and analog sensor
behaves like an IDS sensor.
The following IDS adapters can be operated on the Multi 9420:
1.2.3 Automatic sensor recognition
The automatic sensor recognition for IDS sensors allows
to operate an IDS sensor with different meters without recalibrating
to operate different IDS sensors at one meter without recalibration
to assign measurement data to an IDS sensor
– Measurement datasets are always stored and output with the sensor
name and sensor series number.
to assign calibration data to an IDS sensor
– Calibration data and calibration history are always stored and output with
the sensor name and sensor series number.
to activate the correct cell constant for conductivity sensors automatically
to hide menus automatically that do not concern this sensor
To be able to use the automatic sensor recognition, a meter that supports the
automatic sensor recognition (e.g. Multi 9420) and a digital IDS sensor are
required.
In digital IDS sensors, sensor data are stored that clearly identify the sensor.
The sensor data are automatically taken over by the meter.
ADA 94/IDS DIN / BNC
(pH / U / ISE)
ADA S7/IDS
(pH / U)
The socket field of the Multi 9420
has a recess where the IDS
adapter (ADA 94/IDS DIN or ADA
94/IDS BNC), which is available as
an accessory, can be permanently
mounted.
In the socket field of the
Multi 9420, the IDS adapter
replaces a digital input (channel 2)
with a socket field for an analog
pH/ U/ISE sensor (DIN or BNC
plug) and a temperature sensor.
The IDS adapter enables to operate
an analog sensor with S7 plug-in
connector on any digital input.
Temperature measurement with an
analog temperature sensor is not
possible.
Information on available IDS adapters is given on the Internet and
in the WTW catalog, "Laboratory and field instrumentation".
Detailed information on the IDS adapter is given in the operating
manual of the adapter.
