General information
The ADA S7/IDS adapter forms an IDS pH sensor in conjunction with a pH
electrode with S7 plug-in connector.
The measuring electronics with the stored adapter data is in the adapter head
of the ADA S7/IDS. The data include, among other things, the adapter type
and series number. With each calibration, the calibration data is written in the
adapter and the calibration history is recorded. The data is recalled by the
meter when the adapter is connected and is used for measurement and for
measured value documentation. Storing the calibration data in the adapter
ensures that the correct slope and asymmetry are automatically used if the
sensor is operated with several meters.
The digital transmission technique guarantees the failure-free communi-
cation with the meter even with long connection cables. If the sensor firmware
is enhanced by WTW, it can be updated via the meter.
Note
More detailed information on the automatic adapter recognition or sensor rec-
ognition is given in the operating manual of the meter.
The connected meter uses for measurement the calibration data stored in the
adapter, regardless of the mounted electrode.
Note
Therefore, you have to calibrate the IDS pH sensor each time the electrode
with the S7 plug-in connector has been exchanged. Otherwise, the IDS pH
sensor will work with the calibration data of the previously used electrode.
This could lead to incorrect measured values. When evaluating the
calibration history, please note that in between calibrations, the electrode
might have been exchanged.
