Prepare the electrode for measuring as follows:
Remove the watering cap from the electrode tip. Possible salt deposits in
the area of the watering cap do not affect the measuring characteristics
and can easily be removed with deionized water.
Connect the sensor to the meter.
The sensor is immediately ready to measure.
Types of connection:
– via a connecting cable (accessory) to a free IDS connector on the meter
or
– wireless via an IDS WLM-S adapter (accessory) to a WLM-capable
meter
or
– via an IDS sensor slot of a multi parameter probe
(connected to a meter)
Accessories for the connection of the SensoLyt
